[CS3] how to move a mc in a class

programming flash
1

this seems so simple, yet I’m having issues with it. I’m starting out simple, all I’m having problems with is repositioning my mc with a function in the class, which is not the document class. here is some code:

package boxes{
	import flash.display.MovieClip;
	public class box0 extends MovieClip{
		
		import flash.display.DisplayObjectContainer;
		public var doc:DisplayObjectContainer;
		static var bs:MovieClip;
		public function box0(){
			bs = new box1(); //box1 is a movie clip
		}
		public function addBox(a:MovieClip){
			a.addChild(bs);
			
		}
			
		public function moveBox(){
		           bs.x = 100;
		}
	}
}

and here is the code on the timeline:

import boxes.box0;
var box:box0= new box0();
box.addBox(this);
box.moveBox();

the box is added to the stage, but is not positioned at 100 !?
any help would be greatly appreciated!!:angry:
