an example, I have 2 repeating block, one for the inventory, an another as a deposit, I add a button to send an item to export item between this two block, and a input to show the weight value. for the HTML code I have : <script data-type="text/worker"> on( "sheet:opened", () => { equipment_weight(); }); // calculate the weight of the equipment on( "change:repeating_equipment:equipment_weight change:repeating_equipment:equipment_quantity remove:repeating_equipment", equipment_weight ); function equipment_weight() { getAttrsRepeating("equipment", ["equipment_weight", "equipment_quantity"], (user_repeating) => { let sum = 0; Object.keys(user_repeating).forEach(id => { sum += user_repeating[id]["equipment_weight"] * user_repeating[id]["equipment_quantity"]; }); // send payload setAttrs({"weight": sum}); }); } // send item to deposit on( "clicked:repeating_equipment:equipment-to-deposit", equipment_to_deposit ); function equipment_to_deposit(event) { let source = event.sourceAttribute.replace(/equipment-to-deposit$/, ''); let target = "repeating_deposit_"+generateRowID()+"_"; getAttrsNumber([source+"equipment_quantity", source+"equipment_weight"], (user_number) => { getAttrs([source+"equipment_label"], (user_string) => { let payload = {}; payload[target+"deposit_label"] = user_string.equipment_label; payload[target+"deposit_weight"] = user_string.equipment_weight; payload[target+"deposit_quantity"] = user_string.equipment_quantity; // send payload setAttrs( payload ); // remove object in equipment removeRepeatingRow(source.slice(0, -1)); }); }); } // send item to inventory on( "clicked:repeating_deposit:deposit-to-equipment", deposit_to_equipment); function deposit_to_equipment(event) { let source = event.sourceAttribute.replace(/deposit-to-inventory$/, ''); let target = "repeating_equipment_"+generateRowID()+"_"; getAttrsNumber([source+"deposit_quantity", source+"deposit_weight"], (user_number) => { getAttrs([source+"deposit_label"], (user_string) => { let payload = {}; payload[target+"equipment_label"] = user_string.deposit_label; payload[target+"equipment_weight"] = user_string.deposit_weight; payload[target+"equipment_quantity"] = user_string.deposit_quantity; // send payload setAttrs( payload ); // remove object in deposit removeRepeatingRow(source.slice(0, -1)); }); }); } // ------------------------------------------ // sub functions // ------------------------------------------ // get all attribute name and their value as getAttrs() // return cleaned numbers function getAttrsNumber(attr, callback) { if ( !Array.isArray(attr) ) attr = [attr]; if ( !(callback instanceof Function) ) callback = () => {}; getAttrs(attr, (payload) => { Object.keys(payload).forEach( key => { payload[key] = parseNumber(payload[key]) }); callback(payload); }); } // get all attributes name and their values from a repeating block ordered by Id (roll20 generated) // return cleaned numbers function getAttrsRepeating(section, fields, callback) { section = section.replace(/^repeating_/g, ''); if ( !Array.isArray(fields) ) fields = [fields]; if ( !(callback instanceof Function) ) callback = () => {}; // get data from DOM // note : we work on raw data and not with initialized variables // because we don't know what "getAttrs" produce getSectionIDs(section, id => { // prepares attributes name for "getAttrs" let attributeNames = id.reduce( (m,id) => [...m, ...(fields.map(field => "repeating_"+section+'_'+id+'_'+field))],[]); getAttrs(attributeNames, raw => { let payload = {}, regex = new RegExp( "repeating_" + section + "_([^_]*)_(.*)"), match; Object.keys(raw).forEach( key => { match = key.match(regex); if ( !payload.hasOwnProperty( match[1]) ) payload[ match[1] ] = {}; payload[ match[1] ][ match[2] ] = parseNumber( raw[key] ); }); callback(payload); }); }); } // parse and clean numbers from roll20 // ( checkbox from roll20 return "on" for TRUE, 0 for FALSE ) function parseNumber(value) { if ( value === "" ) return null; return parseFloat(value) || (value === "on" ? 1 : 0); } </script> weight : <input name="attr_weight" value="0" title=""> <div> <fieldset class="repeating_equipment"> <table> <tbody> <tr> <td> <input type="text" name="attr_equipment_label" title="" /> </td> <td> <input type="number" name="attr_equipment_weight" title="" /> </td> <td> <input type="number" name="attr_equipment_quantity" title="" /> </td> <td> <button type="action" name="act_equipment-to-deposit">send</button> </td> </tr> </tbody> </table> </fieldset> </div> <div> <fieldset class="repeating_deposit"> <table> <tbody> <tr> <td> <input type="text" name="attr_deposit_label" title="" /> </td> <td> <input type="number" name="attr_deposit_weight" title="" /> </td> <td> <input type="number" name="attr_deposit_quantity" title="" /> </td> <td> <button type="action" name="act_deposit-to-equipment">send</button> </td> </tr> </tbody> </table> </fieldset> </div> There is no function for deposit ( because I don't calculate the weight for items in the deposit ) So as I said, when I click on the button, the item is send to the deposit, the weight of the item in inventory is correctly recalculated ( equipment_weight() is executed because of removeRepeatingRow() command ). But when I click on the button in the deposit, the weight of the item is not added to the total weight ( equipment() is not executed, change: repeating_equipment:equipment_weight is not triggered ) I already got a solution, as I use a separate function for the callback so I can change in the function deposit_to_inventory() : setAttrs( payload ); to setAttrs( payload, {silent:true}, equipment_weight); But it is not the same the logic with the events change and remove a new event add , or modify the event remove can be a good way of thinking
