Remove MovieClip

Hi there,

I want to remove two movieclips at once, with one function but I can not get it to work. Some help would be appreciated!


    function createLightBox(){
        var ol:overlay = new overlay();
        ol.scaleX = stage.width;
        ol.scaleY = stage.height;
        addChild(ol);
        ol.addEventListener(MouseEvent.CLICK, removeLightBox);
        var lb:lbContent = new lbContent();
        ol.stage.addChild(lb);
        lb.x = 800;
        lb.y = 350;
    }
    function removeLightBox(e:MouseEvent):void{
        var targetmc = e.target;
        removeChild(targetmc);
    }

With the above code I am only able to remove the ol movieclip, I need to remove the lb movieclip as well. Does anyone know how to do this?
