I have a textbox list question where respondents have to rank products from 1 to 5 (ranking question types won’t work for my client). I know that I can restrict their answers to only allow 1,2,3,4 or 5, but how can I restrict it so they can’t put the same number in more than one textbox. So if they put 1,2,2,3,3 or 1,2,3,3,4 it still allows them to go through at the moment, but I only want them to be able to put each number in once.
SurveyGizmo does not have this built in capability for the question type that you are using (the ranking questions are designed for this, but as you mentioned this will not work in your case).
I hope this helps!
