Buttons in movieClip

I have a movieClip on the main stage that plays on rollover.
In the last from of the movieClip are my buttons, but they dont work.
There’s not even any AS on them yet, they simipily wont go to their over frame.

Here’s the code in the first fame of the MC:

stop();

this.onEnterFrame = function(){
if(rewind == true){ p
revFrame(); }
}

this.onRollOver = function(){
rewind = false;
backwards…
play();
}

this.onRollOut = function(){
rewind = true;

So on the last frame of the MC is a stop(); and my buttons with no script on them, but a simple block of color should appear when the mouse is over them.
I suspect it has something to do with the MC and the button both needing to recognize where the mouse is, but I’m not certain.
Thoughts?
