Disarming the drag

programming flash

I have a movieclip with a drag/drop script with it and once dropped in a specific target, it goes to a specific frame. Works fine.
My question is how can one stop the drag feature once it is in the proper location? I tried using stopDrag(); but this doesn’t seem to work outright.

The name of my movieclips are price1, area1, and area2.

Here’s the code for one of the buttons:

on (press) {
	startDrag("_root.price1");
}
on (release) {
	stopDrag();
	if (_root.price1._droptarget == "/area1") {
		_root.area1.gotoAndPlay(2);
	}
	if (_root.price1._droptarget == "/area2") {
		_root.area2.gotoAndPlay(22);
	}
