Caption rollOver help

[typeofdoug]

I've pieced this together from a tutorial on captions. My goal is for a caption to pop up in a customized balloon when the user rolls over a button. I'd also like the balloon to feel like it's stuck to the end of the mouse while in the button's hitspace.

I think the way to do the above is through a startDrag and alpha property script.

I'm having trouble getting the correct captions to turn off and on (alpha) over the right buttons.

Plus, I'd like to gather all the script into the first layer and just reference my movieClips and buttons.

This is what I have on my first frame actions layer:

timeline2.captionMoon.startDrag( true);

timeline2.captionShip.startDrag( true);

I've placed this code on each caption moviClip

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

And this on the button the caption is supposed to stick too

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

I know this is confusing. Well at least to me. So here's my fla file:
