Quick question (noob)

K so I have a movieclip called ‘player’ and within that movieclip i have one called ‘close’.

on ‘close’ I have the following AS :

on (release) {
	this._parent._visible = false;
}

why isnt this working? I feel so dumb because it’s such a small bit of code :confused:
I tried accessing it though ‘_root.player’ as well, that didnt work either.
