I’m not really experimented with Actionscript and I was wondering why my script wasn’t working. Anyone can help me please?

on (press) {
	startDrag("_root.La_princesse");
}
on (release) {
	stopDrag();
	if (_root.La_princesse._droptarget == "/case_bleu1")
		_root.case_bleu1.move(x:120.9, y:40.0);
	else
		_root.case_bleu1.move(x:693.9, y:40.0); 
}
