    Can I make it so that an answer can only be used once?

    Asked by brandonppr on July 24, 2017 at 06:55 PM


    Form user 1 enters "1452" as an answer and submits it

    Form user 2 enters "785" as an answer and submits it

    Form user 3 enters "1452" as an answer but is told that answer has already been used and cannot continue until another number has been chosen


    Is that possible?

    That's possible when you enable unique question to a field.
