I have a simple loop that duplicates a movieclip. I have 2 frames within this mc and I am trying to play frame 2 when mouse roll over. I am trying to add a mouse\_over listener and keep receiving an error: brief account of my code is:

```auto
for (var i:Number=0; i<10; i++)
	{

		var item:NewItem = new NewItem();
		item.name = "item" + i;

		MainItem.addChild(item);

                item.x = xPos;
		xPos += (70*2 + 15);
				item.button.addEventListener(MouseEvent.MOUSE_OVER, controlOver);	
	
}

function controlOver(e:MouseEvent):void
{

	MovieClip(parent).gotoAndStop(2);	
}

```

when I try and rollover the item I receive:

TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Stage@36ccd089 to flash.display.MovieClip.at forloopas3\_fla::MainTimeline/controlOver()

How can I get this working for me?

Thanks
