Swap depth?

hey,
flash cs3, as2, i have a movie clip that is a panel composed of multiple little image, in this MC each little image is a MC itself, with this code on:
*onClipEvent(enterFrame){
if(this.hitTest(_root._xmouse, _root._ymouse)){
this.nextFrame();

}
else {
this.prevFrame();
}

}*

in each of this lil MC you have a rollover animation, that brings the concerned image to the center of the stage and then scale up,
my pb is that this animation happens behind the movie clip, how do i bring it in front?
heeeeeeelp!
thanks:angel:

Im not completely sure.

I think the best way is to create emptyMovieClip on different levels and call upon certain mc’s

EDIT:
Lol I just re-read what I wrote and it makes no sense… good luck with that!
