im getting the following error

ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.  
at flash.display:isplayObjectContainer/removeChild()  
at guide\_fla::memb2\_13/frame1()  
at flash.display::MovieClip/gotoAndStop()  
at guide\_fla::memb3\_14/active()

from this section of code

```auto
var mem2:m2 = new m2();
stop();
if(MovieClip(root).c>0){
	this.parent.removeChild(mem2);
}

this.addEventListener(MouseEvent.MOUSE_DOWN, active);
function active (e:MouseEvent):void {
	this.gotoAndStop(2);
	MovieClip(parent).memb1.gotoAndStop(1);
	MovieClip(parent).memb3.gotoAndStop(1);
	MovieClip(parent).memb4.gotoAndStop(1);
	MovieClip(parent).addChild(mem2);
	mem2.x = 280;
	mem2.y = 140;
	var c:int = 0;
	MovieClip(root).c = 1;
}

```

there is also a variable c on the root timeline.  
can anyone tell me why im getting this error?
