Drag and drop matching game... again (sorry)!

Firstly, well noticed on the bad spelling

So to pickup an object;

function pickupObject(event: MouseEvent): void {

  event.currentTarget.startDrag();

  event.currentTarget.parent.addChild(event.currentTarget);

  objectoriginalX = event.currentTarget.x;

  objectoriginalY = event.currentTarget.y;

}

To drop an object;

function dropObject(event: MouseEvent): void {

  event.currentTarget.stopDrag();

  var matchingTargetName: String = "target" + event.currentTarget.name;

  var matchingTarget: DisplayObject = getChildByName(matchingTargetName);

  if (event.currentTarget.dropTarget != null && event.currentTarget.dropTarget.parent == matchingTarget) {

  event.currentTarget.removeEventListener(MouseEvent.MOUSE_DOWN, pickupObject);

  event.currentTarget.removeEventListener(MouseEvent.MOUSE_UP, dropObject);

  event.currentTarget.buttonMode = false;

  event.currentTarget.x = matchingTarget.x;

  event.currentTarget.y = matchingTarget.y;

  } else {

  event.currentTarget.x = objectoriginalX;

  event.currentTarget.y = objectoriginalY;

  }

}

Thanks
