Increment repeating section radio button value

Currently, I have static HTML content with 15 weapons and a radio button for each weapon to detect which one is currently equipped. The information for the equipped weapon is used in the roll buttons for various attack and damage buttons with the weapon.     <input type="radio" class="sheet-toggle sheet-1col" name="attr_Weapon_MainHand_Equipped" value="1" checked />     <p class="sheet-toggle sheet-1col">Main</p>     <input type="radio" class="sheet-toggle sheet-1col" name="attr_Weapon_OffHand_Equipped" value="1" checked />     <p class="sheet-toggle sheet-1col">Off</p> I'd like to increment the value of the radio button, or, if possible, set it to the repeating section id. That way I can look it up on change with a sheet worker script and get the right values.
