Survey123 Connect, Constraint, Answer does not equal to list from file

[SophieSanders]

Hello,

Does anyone know how to apply a constraint so that answer cannot be an ID pulled from a file.csv list,

like the opposite of select one from file, e.g. constraint cannot be from file list,

Many thanks,

A little more info would be helpful. Do you mean something like...

• You have an external list that you don't want user to select from? E.g., Text_Box_1 != list.csv
• You have a repeat with a dropdown that users can select from and you don't want them adding duplicates to the repeat?

Hi abureaux,

Your first suggest is exactly what I needed, I hadn't been including the text_box_name 

I've now used this in the constraints field and it worked!, thank you for your help ${Text_box_name} !=list.csv
