Multiple choice quiz

What up.

I’m using the quiz template supplied by Flash. I’m trying to create a multiple choice quiz, but I don’t want the user to be able to select multiple answers, just one. I thought about using radio buttons instead, but I’m not sure how to customize the pre built quiz components.

Is there a way that when the user selects one answer, he/she cannot select another. And if they change their answer, the previously selected answer would be deselected. Hope that makes sense.

Thanks for the help.
