Item drop

i have this script


		if (drop_itom <= 100 && drop_itom > 0){//9% for money lump  91
			this._parent._parent.attachMovie("money_lump", "money_lump", 1);
			trace("moo")
			this._parent._parent.money_lump._x = this._x
			this._parent._parent.money_lump._y = this._y
		}

but have found that anything i put after the attachMovie just plane refuses to work. Is there another way to change the x and y of the created move. The move that this is in and it’s parent is removed after this happens
