Navigating to MainTimeline from a MovieClip

[da_hammer]

Hello,

Am a newbie to AS 3.0, am trying access the MainTimeLine from a movieClip instance added from Library.
Am able to remove the same instance, but am not able to navigate to MainTim

// Doesn't Work
wellPlayed(root).gotoAndStop(120);

// This removal works fine.
parent.removeChild(wellPlayed);

am sure am doing something silly here is the full code:

public class BallMc extends MovieClip
	{
		protected var originalPosition:Point;
		public function BallMc()
		{
			originalPosition = new Point(x, y);
			buttonMode = true;
			addEventListener ( MouseEvent.MOUSE_DOWN, down );
		}
		
		protected function down (event:MouseEvent) :void
		{
			parent.addChild(this);
			startDrag ();
			stage.addEventListener ( MouseEvent.MOUSE_UP, stageUp );
		}
		
		protected function stageUp(event:MouseEvent ):void
		{
			stage.removeEventListener( MouseEvent.MOUSE_UP, stageUp );
			stopDrag();
			
			if( dropTarget )
			{
				if( dropTarget.parent.name == "basket")
				{
					scaleX = scaleY = 0.2;
					alpha = 0.2;
					y = stage.stageHeight - height - 10;
					
					buttonMode = false;
					removeEventListener( MouseEvent.MOUSE_DOWN, down );
					
					var wellPlayed : WellPlayed = new WellPlayed();
					parent.addChild(wellPlayed);
					
					wellPlayed.x = stage.stageWidth / 2;
					wellPlayed.y = stage.stageHeight / 2;	
					
					wellPlayed.addEventListener(MouseEvent.CLICK, wellClick);
					
					function wellClick(event:MouseEvent):void
					{
						wellPlayed(root).gotoAndStop(120);
						parent.removeChild(wellPlayed);
						wellPlayed.removeEventListener(MouseEvent.CLICK, wellClick);
						
					}
			
				}else{
					returnToOriginalPosition();
				}

			}else{
				returnToOriginalPosition();
			}
		}
		
		protected function returnToOriginalPosition():void
		{
			x = originalPosition.x;
			y = originalPosition.y;
		}
		
	}

Someone point me in the right direction.

Thanks in advance.
Amar
