Error generating preview

Dears,

I have the following error when I am trying to generate a preview, noting that the form was working fine and now this error appears

“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”

Could any one help me? what i should do to fix it?

Hello,
You probably have at least one choice (name column) duplicate in your choices sheet.
More info here: https://xlsform.org/en/#choice-names
