adding up repeating fields

Hello everyone, i would like to add up a repeating field, i found an example from Dark Heresy, but somehow it doesn't work and i don't see my mistake. Maybe someone can help me. here the repeating field <div class="sheet-totalxp"> <div class="sheet-formular"> <label for="attr_XPtoSpend">Verfügbare EP</label> <input type="number" class="sheet-number-20" name="attr_XPtoSpend"  value="@{XPTotal} - @{XPSpent}" disabled /> </div> <div class="sheet-formular"> <label for="attr_XPSpent">Ausgegebene EP</label> <input type="number"  class="sheet-number-20" name="attr_XPSpent" disabled /> </div> <div class="sheet-formular"> <label for="attr_XPTotal">Gesamte EP</label> <input type="number" class="sheet-number-20" name="attr_XPTotal" /> </div> </div> <fieldset class="repeating_advancements"> <div class="sheet-item"> <input name="attr_advancement1" type="text"> </div> <div class="sheet-brackets"> <input name="attr_advancement1xp" type="text"> </div> <div class="sheet-item"> <input name="attr_advancement2" type="text"> </div> <div class="sheet-brackets"> <input name="attr_advancement2xp" type="text"> </div> <div class="sheet-item"> <input name="attr_advancement3" type="text"> </div> <div class="sheet-brackets"> <input name="attr_advancement3xp" type="text"> </div> </fieldset> here the js part on('change:repeating_advancements', function(){     TAS.repeating('advancements')           .attrs('XPSpent')           .fields('advancement1xp','advancement2xp', 'advancement3xp')  .reduce(function(memo, row) { memo += (row.I.advancement1xp); memo += (row.I.advancement2xp); memo += (row.I.advancement3xp); return memo; },0,function(memo, row, attrSet) { attrSet.I.XPSpent = memo; }) .execute();  });

Hi Tealk, i'm using the same script in on my sheet. but my worker is a bit different. Try this on('change:repeating_advancements', function(){     TAS.repeating('advancements')  //< set the repeating group we are using         .attrs('XPSpent')  //< specify we want access to the total_weight attribute         .fields('advancement1xp', 'advancement2xp', 'advancement3xp') //< specify we want the item and weight repeating fields          .reduce(function(memo,row,attrSet,id,rowSet)         { memo.total += row.I.advancement1xp; memo.total += row.I.advancement2xp; memo.total += row.I.advancement3xp; return memo;         },{total: 0},function(memo,rowSet,attrSet)         {             attrSet.I.XPSpent = memo.total;         })         .execute();  });

Sorry, also for this to work you need Aaron's TAS script in your html too.. that's probably the issue. <a href="https://github.com/shdwjk/TheAaronSheet/blob/master/TheAaronSheet.js" rel="nofollow">https://github.com/shdwjk/TheAaronSheet/blob/master/TheAaronSheet.js</a>

do I just copy the whole thing or can I link to it somehow?

Yes, copy whole thing in, it needs to be before the repeating worker i believe, mine is anyway.

Thanks for the help, now it works. But it's stupid with the script, because it takes so much space.

If you want a more compact approach, use this function:&nbsp; <a href="https://wiki.roll20.net/RepeatingSum" rel="nofollow">https://wiki.roll20.net/RepeatingSum</a>

Thanks GiGs for the manual, somehow the search didn't give it to me. I will definitely have a look at it.
