Hi folks, novice creating my first custom sheet here. I am trying to have a repeating section to track items, weight (default 1) and total encumbrance (total weight), with a check box to make an items weight=2. I have implemented the repeating sum as per the wiki. Removing an item works and updates the Total Encumbrance Total Encumbrance doesn't update when clicking Add in the repeating section or when clicking the checkbox. Any help understanding what's going on would be appreciated. Thanks! <fieldset class="repeating_inventory"> <span>Name</span> <input type="text" name="attr_itemname"> <span>Bulky</span> <input type="checkbox" name="attr_bulky" value="1"> <span>Weight</span> <input type="number" name="attr_itemweight" value="1 + 1 * @{bulky}" disabled> </fieldset> <br> <span>Total Encumbrance</span> <input type="number" name="attr_encumbrance_total" value="0"> <script type="text/worker"> Function as per the wiki, and the following worker: on('change:repeating_inventory:bulky change:repeating_inventory:itemweight change:repeating_inventory remove:repeating_inventory sheet:opened', function() { repeatingSum("encumbrance_total","inventory","itemweight"); });
