Stop drag and drop in end... and show the end

Question

Hi.
I use the next code for drag and drop. I move item1 for bin1, item2 for bin2 but when i move the item3 for the correct bin3... the solution  everything disappears...
How i can stop the end?
item1.objName = "circle";
item1.initX = item1.x;
item1.initY = item1.y;
item1.val = 0;
item2.objName = "rectangle";
item2.initX = item2.x;
item2.initY = item2.y;
item2.val = 0;
item3.objName = "triangle";
item3.initX = item3.x;
item3.initY = item3.y;
item3.val = 0;
bin1.shape.alpha = 0;
bin2.shape.alpha = 0;
bin3.shape.alpha = 0;
item1.buttonMode = true;
item2.buttonMode = true;
item3.buttonMode = true;
item1.addEventListener(MouseEvent.MOUSE_DOWN, mousePress);
item1.addEventListener(MouseEvent.MOUSE_UP, mouseRelease);
item2.addEventListener(MouseEvent.MOUSE_DOWN, mousePress);
item2.addEventListener(MouseEvent.MOUSE_UP, mouseRelease);
item3.addEventListener(MouseEvent.MOUSE_DOWN, mousePress);
item3.addEventListener(MouseEvent.MOUSE_UP, mouseRelease);
//Mouse Events
function mousePress(event:MouseEvent):void {
          var item:MovieClip = MovieClip(event.target);
          item.startDrag();
          item.scaleX = item.scaleY = .95;
          var topPos:uint = this.numChildren - 1;
          this.setChildIndex(item, topPos);
          ilabel.itemName_txt.text = item.objName;
function mouseRelease(event:MouseEvent):void {
          var item:MovieClip = MovieClip(event.target);
          item.stopDrag();
          switch (item.objName) {
case "circle" :
                    if (bin1.hitTestObject(item)){
                    updateShape(item, bin1);
            else{
                    ilabel.info_txt.text ="WRONG!";
                    item.scaleX = item.scaleY = 1
break;
case "rectangle" :
                    if (bin2.hitTestObject(item)) {
                    updateShape(item, bin2);
                    else{
                    ilabel.info_txt.text ="WRONG!";
                    item.scaleX = item.scaleY = 1
break;
  case "triangle" :
if (bin3.hitTestObject(item)){
                    updateShape(item, bin3);
                    else{
                    ilabel.info_txt.text ="WRONG!";
                    item.scaleX = item.scaleY = 1
break;
  default :;
function updateShape(item:MovieClip, bin:MovieClip):void {
          ilabel.itemName_txt.text = "";
          item.scaleX = item.scaleY = 1;
          item.visible = false;
          ilabel.info_txt.text ="CORRECT!";
          bin.shape.alpha = 1;
          item.val = 1;
          resetShapes();
function resetShapes(){
          if((item1.val == 1)&& (item2.val == 1) && (item3.val == 1)){
                    item1.x = item1.initX;
                    item1.y = item1.initY;
                    item2.x = item2.initX;
                    item2.y = item2.initY;
                    item3.x = item3.initX;
                    item3.y = item3.initY;
                    bin1.shape.alpha = 0;
                    bin2.shape.alpha = 0;
                    bin3.shape.alpha = 0;
                    item1.visible = true;
                    item2.visible = true;
                    item3.visible = true;
                    item1.val = 0;
                    item2.val = 0;
                    item3.val = 0;

Answer 1

i need
bin1.shape.alpha = 0;
bin2.shape.alpha = 0;
bin3.shape.alpha = 0;
for the start.
properly when I put the first ... all OK.
properly when I put the second ... all OK.
the problem is when I correctly put the third ... everything back to start automatically but I do not want.
someone can help me
