Trying to math attrs and failing

Trying to output experience totals for a character sheet by grabbing the initial score but its failing to work for me.  on("change:repeating_ability:Ability_Score", function() { getAttrs([repeating_ability_Score], function(values) { var n = values.repeating_ability_Score; setAttrs({ repeating_ability_AbilityTotal_exp: ((n*(n+1)/2)*5), repeating_ability_AbilityAdvancement_exp: ((n+1)*5); }); }); }); And in case it matters, the relevant line in the repeating fieldset <input type="number" class="sheet-number_2" name="attr_Ability_exp" value="0"/> / <input type="number" class="sheet-number_2" name="attr_AbilityAdvancement_exp" value="0"/> / <input type="number" class="sheet-number_2" name="attr_AbilityTotal_exp" value="0"/>

getAttrs pulls things in as a string, so you need something like: var n = parseInt(values.repeating_ability_Score)||0;

Good to know. It seems right now its not setting the attributes correctly, when I play with the score field its not updating to the exp fields. I was making a wild guess that maybe putting both attributes in the same function might be the problem but that doesn't seem to work either. This is where I'm at now. on("change:repeating_ability:Ability_Score", function() {          getAttrs([repeating_ability_Score], function(values) {         var n = parseInt(values.repeating_ability_Score)||0;         setAttrs({repeating_ability_AbilityTotal_exp: ((n*(n+1)/2)*5)});         setAttrs({repeating_ability_AbilityAdvancement_exp: ((n+1)*5)});     }); });

I see a couple of problems. This:  on("change:repeating_ability:Ability_Score suggests you have field names repeating_ability_Ability_Score but later you use "repeating_ability_Score" - those two fields don't match up. Also, in the change line, you can't use capitals, so that first line should be one of these: on("change:repeating_ability:ability_score // or on("change:repeating_ability:score // so this line var n = parseInt(values.repeating_ability_Score)||0; // might be wrong, and maybe should be var n = parseInt(values.repeating_ability_Ability_Score)||0; I cant tell which of those statements is correct, and which one's wrong, without seeing the repeating set's html. Btw, you still use capital letters in the other places, but you must drop everything to lower case in the on() line. Your SetAttrs statements should also be combined, like this: setAttrs({ repeating_ability_AbilityTotal_exp: ((n*(n+1)/2)*5),      repeating_ability_AbilityAdvancement_exp: ((n+1)*5) }); Also, another syntax note. In your first post, you had this: setAttrs({ repeating_ability_AbilityTotal_exp: ((n*(n+1)/2)*5), repeating_ability_AbilityAdvancement_exp: ((n+1)*5); }); That semi-colon inside the setattrs brackets shouldn't be there. Refer back to the version I posted just above.

I've made the suggested changes, still no bueno T_T I'm going to post the full fieldset then.  The relevant attributes: attr_Ability_Score attr_AbilityAdvancement_exp attr_AbilityTotal_exp <fieldset class="repeating_ability">                     <table class="sheet-table_2" style="width:400px;">                         <tr>                             <td width="30px"><button type="roll" class="sheet-button" name="roll_ability" value="&{template:ability} {{name= @{character_name}}} {{label4=Circumstances}} {{result4=[[(?{Circumstantial|0})]]}} {{label0=@{Ability_name}}} {{banner=@{Ability_Speciality}}} {{label1=Rank}} {{result1= [[ @{Ability_Score} + @{Ability_Puissant} ]]}} {{label2=Characteristic}} {{result2=[[@{Ability_Characteristic}]]}} {{label3=Weakness}} {{result3=[[@{Fatigue} + @{wound_total}]]}} {{result0=[[ 1d10 + @{Ability_Score} + @{Ability_Puissant} + @{Ability_Characteristic} + @{wound_total} + @{Fatigue} + (?{Circumstantial|0})]]}}"></button></td>                                                         <td width="240px"><input type="text" style="width:220px;" class="sheet-heading_4" name="attr_Ability_name"/></td>                             <td><input type="number" class="sheet-number_2" name="attr_Ability_TotalScore" value="[[(@{Ability_Score}) + (@{Ability_Puissant})]]" disabled="true" /></td>                             <th><div style="width:40px;"><input type="checkbox" class="sheet-hider sheet-checkbox_1" name="attr_Ability_show" value="1" checked/><span></span></div></th>                         </tr>                     </table>                     <input type="checkbox" class="sheet-hider sheet-hidden" value="1" name="attr_Ability_show" checked/>                     <div class="sheet-hide">                         <table class="sheet-table_2" style="width:400px;">                             <tr>                                 <th>Characteristic</th>                                 <th>Speciality</th>                                 <th>Score</th>                                 <th>Bonus</th>                             </tr>                             <tr>                                 <td>                                     <select class="sheet-select_1" name="attr_Ability_Characteristic">                                         <option class="sheet-italic" value="0">Characteristic</option>                                         <option value="@{Intelligence_Score}">Intelligence</option>                                         <option value="@{Perception_Score}">Perception</option>                                         <option value="@{Strength_Score}">Strength</option>                                         <option value="@{Stamina_Score}">Stamina</option>                                         <option value="@{Presence_Score}">Presence</option>                                         <option value="@{Communication_Score}">Communication</option>                                         <option value="@{Dexterity_Score}">Dexterity</option>                                         <option value="@{Quickness_Score}">Quickness</option>                                     </select>                                 </td>                                 <td><input type="text" class="sheet-heading_4" name="attr_Ability_Speciality" placeholder="Speciality" /></td>                                 <td><input type="number" class="sheet-number_2" name="attr_Ability_Score" value="0"/></td>                                 <td><input type="text" class="sheet-number_2" name="attr_Ability_Puissant" value="0"/><span></span></td>                             </tr>                             <tr>                                 <th style="text-align: right;">XP</th>                                 <td colspan="3">[<input type="number" class="sheet-number_2" name="attr_Ability_exp" value="0"/> / <input type="number" class="sheet-number_2" name="attr_AbilityAdvancement_exp" value="0"/> / <input type="number" class="sheet-number_2" name="attr_AbilityTotal_exp" value="0"/>]</td>                             </tr>                         </table>                     </div>                 </fieldset> Here's the present script on("change:repeating_ability:ability_score", function() {     getAttrs([repeating_ability_Ability_Score], function(values) {         var n = parseInt(values.repeating_ability_Ability_Score)||0;         setAttrs({             repeating_ability_AbilityTotal_exp: ((n*(n+1)/2)*5),             repeating_ability_AbilityAdvancement_exp: ((n+1)*5)         });     }); });

ITS A CHRISTMAS MIRACLE. Thanks everyone, you save me again. 

Can I set values to attributes that I've spliced together like this? on("change:creo_score change:intellego_score change:muto_score change:perdo_score change:rego_score change:animal_score change:aquam_score change:auram_score  change:corpus_score change:herbam_score change:ignem_score change:imaginem_score change:mentem_score change:terram_score change:vim_score", function(eventInfo)) {     var art = eventInfo.sourceAttribute;     getAttrs([art], function(values)) {         var n = parseInt(values.art)||0;         setAttrs({             art + "_exp" = (n+1),             art + "_exp2" = (n*(n+1)/2)         });     }); }); The idea being that I can find the root attribute and make changes to attributes based off the of the root. 

Can I set values to attributes that I've spliced together like this? Absolutely, if you want calculated property names in object literals, you just need to wrap them in square brackets like this (and no equal signs, that is not how object literals work). However, values.art will access the property name "art"; instead, you will want to use values[art].         var n = parseInt(values[art])||0; setAttrs({             [art + "_exp"]: (n+1),             [art + "_exp2"]: (n*(n+1)/2)         }); You could also register one event per attribute: ['creo', 'intellego', 'muto', 'perdo', 'rego', 'animal', 'aquam', 'auram', 'corpus', 'herbam', 'ignem', 'imaginem', 'mentem', 'terram', 'vim'].forEach(function (name) { on("change:" + name + "_score", function () {     getAttrs([name + "_score"], function(values) { const n = parseInt(values[name + "_score"])||0;       setAttrs({             [name + "_score_exp"]: (n+1),             [name + "_score_exp2"]: (n*(n+1)/2)       });     }); }); });
