Problem with the colouring book tutorial

Hi. I have made my own colouring thingy using the kirupa tutorial, which works fine when exported on its own. The problem is when i call it into a parent movie, the brush doesnt show up on the stage. The mouse is hidden, and the colouring still works (when i guess where to click), but as i said i cant see the brush.

I got this far by using this.blahblah instead of _root.blahblah but cant get any further.

Any help greatly appreciated.
