When I try to preview my form, I get the following error:
There does not seem to be a
allow_choice_duplicates column header defined in your settings sheet. You must have set
allow_choice_duplicates setting in your settings sheet to have duplicate choice list names in your choices sheet
I don’t understand where it’s coming from, as the form has been used a few months ago already, and I’ve now only added a few additional questions.
Does anyone know how to resolve this issue?
Thanks in advance.
