I'm having a problem making a few things work right together

ok so there are two movies, 1 is the parent movie the other is a background image that is dynamically loaded into the parent.

in the first frame of the parent movie:

choice = Math.round(Math.random()*0);
	switch (choice) {
	case 0 :
		blank.loadMovie("flash/image1.swf");
		break;
	}

and

Stage.scaleMode = "noScale";
Stage.align = "LT";

and in the first frame on the background MC:

this.resizable_mc._width = Stage.width;
this.resizable_mc._height = Stage.height;
this.resizable_mc._x = this.resizable_mc._y = 0;
this.resizable_mc.onResize = function() {
        this._width = this.width;
        this._height = this.height;
};
Stage.addListener(this.resizable_mc);

as you can see im trying to dynamically load a background image that will be 100% of the browser window size, it isnt working however!

thanks for anyones help! C:-)
