In the box next to values with, pick the formatting you want to apply to the duplicate values, and then click OK.
However, I found no duplicates and yet my survey says
“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”
How can I solve this problem?
P.S. I also want to share my xls. in advance, but I can’t upload my xls. in kobo…
