In a screen, I have a procedure where inside there are 4 questions and their respective answers, in which what the procedure does is to choose one at random. But, what I want to do is that when I choose a question and the person answers it, that question is eliminated so that it does not appear again. The problem is that every time I go back to that screen, the procedure generates the list at random with the four questions again.
PS: The easier the syntax the better.
I hope you can help me 
Thanksssss
