```auto
plate.addEventListener(MouseEvent.MOUSE_DOWN, drag);
plate.addEventListener(MouseEvent.MOUSE_UP, noDrag);
plateBlur.mask = plate.plateMask;
function drag(event:MouseEvent):void {
    plate.startDrag();
}
function noDrag(event:MouseEvent):void {
    plate.stopDrag();
}
stop();

```

The movieClip plate drags around the stage on mouse down but the movieClip plateMask (which is inside plate) doesn’t move with plate. How can i fix this?  
Sorry if this is stupid question, i’m new to as3 and still getting used to the difference between as2 and as3.
