Unloadmovie

1

This is what i’ve done, but the thing is that’s not working. When I try this code the mail_mc never shows, and if I try to change it, it never goes away!
any tips on which way to go ?

onClipEvent (enterFrame) {
	if (_root.btn_3, hitTest(_root.head)) {
		_root.createEmptyMovieClip("mail_mc", 65);
		this.loadMovie("mail.swf", "mail_mc") 
		this._x = "230";
		this._y = "190";
		
	} else {
		this.unloadMovie("mail_mc");
	}
}
