Targeting a child movieClip in AS2

so I am building a image scroller, that is fairly simple, but I am really having a hard time with targeting the clips inside the main clip. Here is the code that makes the scroller either visible or not :

mouseOverClip.onRollOver = function() {

TweenLite.to(mouseOverClip, .5, {_y:107});
mouseOverClip.rotateImg.gotoAndPlay(2);

}

mouseOverClip.onRollOut = function() {

TweenLite.to(mouseOverClip, .5, {_y:181});

}

now in mouseOverClip, I have a clip called clipA that I need to perform a function when the mouse rolls over, however since the mouseOverClip is “listening” for the mouse over/out, its ignoring clipA. someone help! Im thinking there should be logic inside the rollOver to check what clip im over and to perform a function if that is true…
