AS3: The supplied DisplayObject must be a child of the caller

Question

I can't figure this one out, i'm sorry - really an ActionScript noobie here. I've searched for the problem but the answers i keep finding don't solve my problems. Anyone know whats wrong?

public function KikkerOgen() 
        {
            addEventListener(MouseEvent.CLICK, isClicked);
            timer.addEventListener(TimerEvent.TIMER, Knipperen);
            timer.start();
            gotoAndStop(13);
        }

        function isClicked (event:MouseEvent):void 
        {
            removeChild(this);
        }

Answer 1

Sorry your problem is in:

removeChild(this);

You are trying to remove the object from the object itself!!!

That's what you should do:

this.parent.removeChild(this);
