Hi everyone, We’ve just posted a sheetworkers bug fix to the dev server for testing and would love for you to check it out. Essentially, the problem was that on() event listeners were not selecting the correct attributes of repeating sections when passed in as the arguments of the listener. Also, the parent repeating section scope itself should be available in that same event. On the dev server, t he following code should now trigger both the parent repeating_test section and the receiver_1 attribute child of the repeating section. <fieldset class='repeating_test'> <input type='text' name='attr_receiver_1' value=''> <input type='text' name='attr_receiver_2' value=''> <input type='text' name='attr_receiver_3' value=''> <input type='text' name='attr_receiver_4' value=''> </fieldset> <script type='text/worker'> on('change:repeating_test:receiver_1', (event)=>{ console.table(event); }); </script> As you take a look at this on the dev server , we would ask that you please check to see that this bug has been fixed, but also that other sheetworkers for your sheets are working as intended and no other adverse effects are found. If you do find anything strange with sheetworkers or repeating sections, please let us know in the thread. Thanks!
