Flash Quiz Drag and drop help

Hello, I have a Quiz where you drag a symbol over the correct answer, I have got it to work for a single question but I can't figure out how to get it to reset and work on the next frame with the new question.

Once the perosn chooses the correct answer a button apears allowing them to click onto the next question, if they get the wrong one then it shows the game over animation.In total I have 5 questions and after your get the final queston correct it shoudl go to a new frame where the winner animation plays. I'm not very good with scripting, sorry.
