Hello,
I'm currently working on adding security questions to user registration, I have three different questions in the drop down list, I want to have them validate in a way so that the user can only select a particular question once.
I've tried using the built in validation rules for "compare to another field" and checking if the value equals that of the other questions but this just results in them only validating when they are the same questions?
What is the best way to go about doing this? Thanks
