[CS3] how to move a mc in a class

[Gar_Fonz]

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:

Nevermind, it works, I forgot that I centered the clip around the registration point of the click, oops
