List Component

Hello, i have the following code in which im trying to add an item in a List Component which instance has been named “box”. That “trace” function used there returns me “_level0.Game.replayMenu.box”, so im not pointing to something undefined…

this = _root.Game.ui;
this._parent.attachMovie (“replayMenu”,“replayMenu”,this._parent.getNextHighestDepth ());
this._parent.replayMenu._x = 450;
this._parent.replayMenu._y = 250;
trace(this._parent.replayMenu.box);
this._parent.replayMenu.box.addItem(“blablabla”,“blablabla”);

The problem is that my list simply doesn´t add any items at all, i’ve already tried using addItem({label:“blablabla”, data:“blablabla”}), but it just don´t work.

Thanks, hope someone can help me…
