Addressing _ldr from mc

Hi

I have the instance ‘CONTENT_ldr’ on the main timeline. Now I need to load an swf into it using AS when I press on the ‘Illu_mc’ button placed in my HomeMenu_mc.
Heres the script I have placed in my HomeMenu_mc:

this.Illu_mc.onRelease = function() {
this._parent.CONTENT_ldr.contentPath = “ILLUPROJ.swf”;
};

Where am I going wrong?
