When I click the “Edit in Form Builder” to edit my deployed XLSForm, I get an error message: “Error loading survey: cascading choices can only reference one choice list”.
Can you help me resolve this problem. Check the screenshot image below.
Thank you.
@bridey28, are you trying to use cascading select for a select-multiple question type?
Yes I have select-multiple type questions in my survey.
This error usually appears when your cascading select is referencing more than one choice list in the choices sheet.
Cascading must use a single list_name, and the child question should filter from that same list using choice_filter. If you mixed lists or tried cascading with select_multiple, the Form Builder will fail to load.
Check your XLSForm and make sure the parent and child questions pull from one list only, and that the filter column exists in that same list. Reupload after correcting it.
