Clear() doesn't work?

Question

Why doesn't my clear function work?
I've tried everything but just can't seem to reference the newly drawn line....
var score:Number = 0;
var startX:Number;
var startY:Number;
var startLineX:Number;
var startLineY:Number;
setup(circleMc);
setup(squreMc);
setup(errowMc);
setup(polygonMc);
//add function for submitBtn button
submitBtn.addEventListener(MouseEvent.MOUSE_DOWN, checkScore);
//function for checking whats right and wrong
function checkScore(event:MouseEvent):void {
     if (circleMc.placedCorrectly == undefined) {
          //if the object is anywhere except where it should be clear the line
                circleMc.graphics.clear();
          circleMc.x = 114;
          circleMc.y = 135;
     if (squreMc.placedCorrectly == undefined) {
          //if the object is anywhere except where it should be clear the line
                squreMc.graphics.clear()
             squreMc.x = 114;          squreMc.y = 205;
     if (errowMc.placedCorrectly == undefined) {
          //if the object is anywhere except where it should be clear the line
          errowMc.x = 114;
          errowMc.y = 275;
     if (polygonMc.placedCorrectly == undefined) {
          //if the object is anywhere except where it should be clear the line
          polygonMc.x = 114;
          polygonMc.y = 354;
function setup(shape:MovieClip):void {
     shape.addEventListener(MouseEvent.MOUSE_DOWN, dragThis);
     shape.addEventListener(MouseEvent.MOUSE_UP, dropThis);
     shape.addChildAt(new Sprite(), 1);
     shape.startX = shape.x;
     shape.startY = shape.y;
     shape.mouseChildren = false;
function dragThis(event:MouseEvent):void {
     event.currentTarget.startDrag(true);
     stage.addEventListener(MouseEvent.MOUSE_MOVE, onMove);
function onMove(m:MouseEvent):void {
     drawLine(MovieClip(m.target));
function drawLine(item:MovieClip):void {
     var line:Sprite = Sprite(item.getChildAt(1));
     var localStart:Point = item.globalToLocal(new Point(item.startX, item.startY));
     var localItem:Point = line.globalToLocal(new Point(item.x, item.y));
     with (line.graphics) {
          clear();
          moveTo(localStart.x, localStart.y);
          lineStyle(2, 0);
          lineTo(localItem.x, localItem.y);
function dropThis(event:MouseEvent):void {
     //stop dragging
     event.target.stopDrag();
     //stop drawing the line
     stage.removeEventListener(MouseEvent.MOUSE_MOVE, onMove);
     //the target MC is named the same as the drag object with the addition of the below prefix
     var myTargetName:String = "target_" + event.currentTarget.name;
     //get dragged object name
     var myTarget:DisplayObject = getChildByName(myTargetName);
     //if you've done it right
     if (event.currentTarget.dropTarget != null && event.currentTarget.dropTarget.parent == myTarget) {
          event.currentTarget.removeEventListener(MouseEvent.MOUSE_DOWN, dragThis);
          event.currentTarget.removeEventListener(MouseEvent.MOUSE_DOWN, dropThis);
          event.currentTarget.placedCorrectly = true;
          event.currentTarget.buttonMode = false;
          event.currentTarget.x = myTarget.x;
          event.currentTarget.y = myTarget.y;
     } else {
          //change result text
          resultTxt.text = "Try Again !";
          //these two command below put the object back where it started at
          //event.currentTarget.x = event.target.startX;
          //event.currentTarget.y = event.target.startY;
          //remove line
          //event.currentTarget.getChildAt(1).graphics.clear();
circleMc.buttonMode = true;
squreMc.buttonMode = true;
errowMc.buttonMode = true;
polygonMc.buttonMode = true;

Sorry for the delay...
You're right.
Forget this post.
I posted the wrong script (a tryout one) and since then, I found my mistake and everything is okay now.
Is there a way to delete this post?
