Random Answer Bank

Hello,

Here's what I'm trying to do...

I've created a flashcard game where each flashcard pulls three locked questions randomly from a question bank. Each question has four answer choices.  

I would like to have the three incorrect answer choices populate from an answer bank so the flashcard is completely different every time.

My initial thought was to have each answer choice as a variable, and then call them into the text field of the answer choice.  However, I would have to refer to a specific variable by name before I could have it display correctly.  Is there a way to have a random variable display in a text field?

Thanks in advance!
