RemoveChild() called on displayed mc to remove itself?

Question

I have the following code that creates and displays graphics by
function called by CLICK event. Then when the user clicks on
one of the created graphics it is supposed to be removed.
function putMarker(name:String, position:Number, xPosition:Number):void
           name is selection title
           position is soundObj position
           xPostion is display object position (relative to knob position at pause point)
          var id:int = selectionMarkers.length;
          var lstId:int = selectionMarkers[id - 1].list.length;
          selectionMarkers[id] = new Object();
          selectionMarkers[id].name = name;
          //trace(selectionMarkers[id].name)
          selectionMarkers[id].list = new Array();
          selectionMarkers[id].list[lstId] = selectionMarkers[id].list[lstId]+':'+position+'|'+xPosition;;
          markers[id] = new Object()//
          markers[id].label = new TextField()
          markers[id].label.text = ''+id; // number
          markers[id].label.width = 1;
          markers[id].label.height = 1;
          markers[id].label.x = 1;        //relative to marker_mc
          markers[id].label.y = 1;
          markers[id].label.setTextFormat(markerLabelForm);
          markers[id].graph = new marker_mc()
          markers[id].graph.x = xPosition + knobmc.width/2;
          markers[id].graph.y = (slt.y + slt.height/2) - markers[id].graph.height;
          markers[id].graph.addEventListener(MouseEvent.CLICK, cutMarker); // << see below
          markers[id].graph.addChild(markers[id].label) //<< this is also questionable
          addChild(markers[id].graph);
// How would I do this? If I use remove(event.target) there error is implicit coercion of
// data types.
function cutMarker(event:MouseEvent):void
          // hide specified marker
          //trace('cutMarker')
          removeChild(this) // if I do stage.removeChild(this) the whole app is removed
         // but I just want to remove the graphic object the event is called on.

Answer 1

I am trying to remove markers[id].graph with the idea that because
markers[id].label
is markers[id].graph's child, it will also be removed.
These objects are held in global array markers, so they do not
disappear when
the function that creates them finishes running. I am thinking I may
have to loop
through this array to find the target object to remove. I am hoping
there will be
a short cut.
