OOP programming problem

Hello,

I have a .as file that creates 6 buttons. For the buttons I have another .as that is their base class (sets the rollover effects). That .as also handles the CLICK event on those buttons.
But nomatter how I try I can’t seem to make it so, that if one of the buttons is clicked it would turn to 3rd .as that would make a MC called “rabbit” on the stage move.

Help please.
