Help please: can't get behavior script to work

Do you know I never really thought about using either mouseenter or
mousemove :)

As I was thinking about various ways to solve my problem it just seemed
'natural' to do something when the mouse was within the button area and I
fixed on that. I will alter my code to use mouseEnter because I like the
simplicity of the behavior not requiring any code in the buttons but I have
learned a useful tip about mouseWithin and mouseMove.

Thanks again.
