reset a button state when retaking a quizz
I have a module with a 'base slide' which has button that link to different videos. once the user clicks the first button and watches the first video it greys out (visited state) which is what I want. However after the person take the quiz and wants to retake the quiz, I want the base slide buttons to return to initial state again, but can't figure out how to do it. I'm attaching copy of one of the modules for you to look at.
