Creating Rollover Effect w/ nested movieclips

I'm using AS2...
Ok so on the main timeline I have two movieclips. One is called exitBtn and one is called back_mc. Then, there is a mc inside of back_mc that's called cta.

I want the cta movieclip to play an animation on a frame labeled "rollOver" when the user rolls over the mc exitBtn.

This is what I currently have on the main timeline (which isn't working)...

Actionscript Code:

exitBtn.on(rollOver){
    back_mc.cta.gotoAndPlay("rollOver");
}

Hi, your function is properly coded. Use the following:

Code:

---

exitBtn.onRollOver = function(){
  // back_mc.cta.gotoAndPlay("rollOver");
  trace("It works");
}

---

Use TRACE to troubleshoot functions to make sure they actually do something.
