Help with Coloring Book [CS5:AS2]

Hi, I followed the tutorial located at:
http://www.kirupa.com/developer/mx2004/coloringbook.htm
to make a Flash coloring book. It appears to be in AS2, so that’s what I made my new one from scratch in.

My coloring book that I’m making (for my company, making educational games for kids) has an image with about 40 fill areas and just two colors (it’s a math game). It also has a button that is supposed to clear their coloring from the board so the next kid can try (these will eventually be used with an interactive whiteboard) and a second button that pops up a small image of what it should look like when they are finished. It is the buttons that I’m having trouble with. I know how to make buttons do certain things in AS3, but those arguments don’t seem to work in AS2. I did figure out how to make a button that jumps to a new frame or a new scene, but this causes the problem of the “show answer” button erasing the student’s progress. I figured out how to make an object appear when the “show answer” button is pressed, but it disappears when the button is released. And the clear button, I can’t get it to work at all. So, my questions:

  1. How could I add a button to the linked tutorial that would clear the screen of all coloring that has been done?
  2. How could I add a button to the linked tutorial that would pop up an object?
