Multiple hover captions

I followed the hover caption tutorial here on kirupa, and it seems that i can’t have more than 1 mc act as a caption.

So far i got 2 mc’s, caption1, and caption 2.

caption1 has the following Actionscript on it:


onClipEvent (enterFrame) {
      if (_root.x==1) {
            this._alpha = 100;
      } else {
            this._alpha = 0;
      }
}

caption2 has:


onClipEvent (enterFrame) {
      if (_root.x==2) {
            this._alpha = 100;
      } else {
            this._alpha = 0;
      }
}

The Actionscript i have on the root timeline is:


startDrag(_root.caption1, true);
startDrag(_root.caption2, true);

Then on the Movieclips that i want the captions to appear, on the first one corresponding to caption1 i got:


on (rollOver) {
	gotoAndPlay(2);
	_root.x = 1;
}
on (rollOut) {
	gotoAndPlay(42);
	_root.x = 0;
}

And caption2:


on (rollOver) {
	gotoAndPlay(2);
	_root.x = 2;
}
on (rollOut) {
	gotoAndPlay(42);
	_root.x = 0;
}

Only the second caption (caption2) appears, but if i remove the actionscript for it on the timeline, the first one appears ?

Thanks,
