Help with roll button.

I am working on a custom character sheet. Trying to make a roll button in a repeating section to roll a specific dice based on the selected character modified combat rating and the targets combat rating. This is what I have (which is not working): <!-- Skil repeating section --> <fieldset class="repeating_skills"> <!-- This checkbox acts as the trigger for the sheet worker --> <input type="checkbox" name="attr_roll_trigger" class="sheet-roll-trigger">     <!-- The button looks like a roll button but just toggles the checkbox --> <button type="roll" name="roll_combat_prompt" value="[[ ?{Enter Target|0} ]] @{temp_target_rating} @{roll_trigger}">Roll</button> <!-- Rest of fieldset --> <input type="text" name="attr_skill_name" placeholder="Skill Name"> <input type="number" name="attr_skill_level" placeholder="Lvl"> <input type="number" name="attr_skill_xp" placeholder="XP"> <input type="number" name="attr_skill_cost" placeholder="AP"> <input type="number" name="attr_skill_end" placeholder="EC"> <input type="text" name="attr_skill_info" placeholder="Skill Info"> </fieldset> // Sheet worker // // Combat Roll // on('change:repeating_skills:roll_trigger', (eventInfo) => {     // Get attributes for the specific row that triggered the change     getAttrs(['temp_target_rating', 'base_cr', 'repeating_skills_skill_name', 'repeating_skills_skill_level'], (values) => {         const target = parseFloat(values.temp_target_rating) || 0;         const base = parseFloat(values.base_cr) || 0;         const bonus = parseFloat(values.repeating_skills_skill_level) || 0;         const name = values.repeating_skills_skill_name || "Combat Check";                  const modified = base + bonus || 1;         const ratio = target / modified; console.log(ratio)         // Dice selection logic         let dice = "1d20";         if (ratio < 0.25) dice = "0";         else if (ratio < 0.5) dice = "1d4";         else if (ratio < 1) dice = "1d6";         else if (ratio < 2) dice = "1d8";         else if (ratio < 4) dice = "1d10";         else if (ratio < 8) dice = "1d12";         const rollString = `&{template:combat} {{name=${name}}} {{target=${target}}} {{modified=${modified}}} {{roll=[[${dice}]]}}`;                  startRoll(rollString, (results) => {             finishRoll(results.rollId, { roll: results.results.roll.result });                          // RESET the checkbox so it can be clicked again             setAttrs({ "repeating_skills_roll_trigger": "0" }, { silent: true });         });     }); }); //Roll template <rolltemplate class="sheet-rolltemplate-combat">     <div class="sheet-container">         <div class="sheet-header">{{name}}</div>         <div class="sheet-row">             <span>Target:</span> <span>{{target}}</span>         </div>         <div class="sheet-row">             <span>Modified Skill:</span> <span>{{modified}}</span>         </div>         <div class="sheet-row sheet-result">             <span>Result:</span> <span>{{computed::roll}}</span>         </div>     </div> </rolltemplate> When I press the button I get the prompt ok, but what gets displayed in Roll20 is:  9  0 on ( [[ ?{Enter Target|0} ]] @{Ukle|temp_target_rating} on)

you are getting that output because that is what you have entered in the roll button. To trigger a sheetworker, you want to use an action button instead of the roll button/checkbox hack. <button type="action" name="act_roll-trigger">Roll</button> on('change:repeating_skills:roll-trigger', (eventInfo) => { Note that I changed the underscore to a dash. This is because action buttons in repeating sections will not fire their listener if they have an underscore in the actual button name.

Thanks Scott. So I made the changes:  <button type="action" name="act_roll-trigger" value="[[ ?{Enter Target|0} ]] @{temp_target_rating} @{roll-trigger}">Roll</button> but when I click the button , nothing happens (I did change the sheet-worker name to roll-trigger). No prompt and no roll.

an action button doesn't use the value property at all. You'll need to do the query as part of your roll assembly

Thanks for the information. I got it sorted with that information.
