addChild to the parent from the child?

Hi guys!

I have a main.fla with a MovieClip thats on the timeline that I load a background into!
The Movieclip has an instance name of bg.

Now, I wonder if it´s possible to load another background into that layer/frame/MC from the player.swf that I loaded from the main.swf

I thought

public function bgLoaded(event:Event):void
		{
			this.parent.parent.bg.addChild(this.bgLoader);
			fadeTween = new Tween(event.target.content,"alpha",None.easeOut,0,1,0.5,true);
		}

would do it, but no luck there :frowning:

Any thoughts and any help would be very much appreciated!

Thanks in advance!
