Coloring Book Question [CS5:AS2]

programming flash
1

I’m making a coloring book app, following the basics from the tutorial at:
http://www.kirupa.com/developer/mx2004/coloringbook.htm

I have made my own and need to add two buttons to it: a “clear board” button and a “show answer” button. I am not sure exactly how to do either one. What I have tried so far:

“show answer” buttons:

  1. within the button, add the answer graphic in the correct position on the “down” and “hit” frames of the button - the result of this is that the answer does pop up when the button is pressed, but it goes away as soon as the button is released.
  2. make the button gotoandStop on a different frame or a different scene - this almost works, but it also erases the students’ coloring, which is not good

“clear board” buttons:

  1. make the button gotoandStop or gotoandPlay to the first frame of the scene - this will work if I’m on that different scene or frame that the 2nd “show answer” button attempt takes us to, but it doesn’t do anything to erase the coloring that’s been done.

So, can anyone help me make buttons that:

  1. show the answer graphic without erasing the coloring
  2. clear all coloring and the answer graphic from the board (essential restart the flash)

?

Thanks.
