Repeating Sum not working

I cannot get the result of a repeatingSum to show. Don't know exactly where the problem resides. I've added the following sheet worker: on('change:repeating_perk remove:repeating_perk', function() { repeatingSum("perk_total","perk","perk_cost"); }); I have a repeating list <fieldset class="repeating_perk"> with <input type="number" name="attr_perk_cost" value="0" /> Here's the line of HTML where I want to display the summed result of all perk costs. <h2>Perks Spent: <span class="input-field-medium"style="width:80%;" name="attr_perk_total"></span></h2> What am I missing?

You might need to add a hidden input for the total.  Not sure if sheetworkers will update a named span alone... ie (used outside within repeating_perk) <input type="hidden" name="attr_perk_total" value="0" >

Thanks, but that didn't seem to help. I suspect its something with the sheet worker. I add this line to check the math of the work, just to see if its calculating, but not displaying. The roll shows 0 for perk total so it doesn't seem to calculate. <label>Perk check: <button type="roll" value="/roll 1d10 + @{perk_total} Roll for Perk"> </button> </label>

I've used repeatingSum in my sheetworkers and your code "looks" fine...  Actually, my hidden input shouldn't be within the repeating section.  Try moving it outside the fieldset.

I tried moving it to a totally different grid in the character sheet. I still get "0" displayed.

Problem found!&nbsp; I thought repeatingSum was built-in functionality. Once I added the "code" from&nbsp; <a href="https://wiki.roll20.net/RepeatingSum" rel="nofollow">https://wiki.roll20.net/RepeatingSum</a> &nbsp;it worked!&nbsp; Sorry to have missed that. But posting it here in case anyone else has the problem.&nbsp; Thanks&nbsp; vÍnce &nbsp;for your quick responses!

Lol.&nbsp; Been down that road more than once. ;-)
