on(dragover) Help please

[Chaos1337]

How do i use the on(dragover), becuase i am making a simple randomness game,(to start off) because i have something that you can drag, and i want to make it if you drag the thing over it it takes you to a new keyframe.
Here is the movie clip i want to be drug on: (nothing happens)

on(dragOver) {
	gotoAndStop(3)
}

Heres the code that you can drag the item(works)

on(press) {
	startDrag(this)
}
on(release) {
	stopDrag()
}

Also, i got music playing, and it only plays once, if i change

Play.onRelease = function() {
	mix1.play();
}

To

Play.onRelease = function() {
	mix1.loop();
}

will it loop?

For the sound, shouldn't you change your function to look like this?

Play.onRelease = function() {
    mix1.start();
} 

Then add this function to the same frame is your existing sound code

mix1.onSoundComplete = function() {
    mix1.start();
}; 

Also there is a good tutorial on droptargets over on Kirupa.
