URGENT - Drag and Drop Game (please help!)

Hi guys, I've been working on a basic Drag and Drop game and i'm very new to AS3 but I was hoping someone out there would be able to help me as my deadline is tonight!

So I've three keyframes on my timeline:

                                                            1st keyframe: Introduction Page

                                                            2nd keyframe: Main Game Page

                                                            3rd keyframe: Score Page

I have three levels for the user to play where they drag and drop three images to their matching images. When the three matches are made it goes to the next level.

I have two arrays. 1. dragArray and 2. matchArray

I tried using the visible= false to hide the level two and level three images while the user plays level one but it isn't working.

Any help would be very very very much appreciated!
