pass over question

Hey folks,

So I have this program that if you drag an object (in this case "circle2") over a predefined place it'll changed into another object ("square"). So this works, but being ambitious or crazy I'd like to have it that if I pass over a second object it'll change into something else. Now my problem is that I've defined a region using an if/else statement. So I can't add a second one or nothing happens. Is it possible to change from the if statement region to if the object (circle2) passes over another another mc? So if the circle passes over target 1 it'll become a square, if it passes over target 2 it'll change into a triangle. Here's my code below, any help would be appreciated.

backbutton.addEventListener(MouseEvent.CLICK, backclick);

helpbutton.addEventListener(MouseEvent.CLICK, helpclick);

answerbutton.addEventListener(MouseEvent.CLICK, answerclick);

circle2.addEventListener(MouseEvent.MOUSE_DOWN, grabMe);

circle.addEventListener(MouseEvent.MOUSE_DOWN, grabMe);

import fl.transitions.TweenEvent;

import flash.display.Sprite;

import flash.events.Event;

//import caurina.transitions.Tweener;

//import com.greensock.*;

import flash.media.Sound;

var me:Object;

function grabMe(e:MouseEvent):void{

me = e.currentTarget;

me.removeEventListener(MouseEvent.MOUSE_DOWN, grabMe);

me.startDrag();

addChild(e.currentTarget as DisplayObject);

stage.addEventListener(MouseEvent.MOUSE_MOVE, dragMe);

stage.addEventListener(MouseEvent.MOUSE_UP, dropMe);

}

function dropMe(e:MouseEvent):void {

stage.removeEventListener(MouseEvent.MOUSE_UP, dropMe);

stage.removeEventListener(MouseEvent.MOUSE_MOVE, dragMe);

me.stopDrag();

me.addEventListener(MouseEvent.MOUSE_DOWN, grabMe);

}

function dragMe(e:MouseEvent):void {

e.updateAfterEvent();

if( me.x >= 291 && me.x <= 633 && me.y >= 311 && me.y <= 690  )

{

  me.gotoAndStop("Square")

}

else

{

   me.gotoAndStop("Circle")

}

}

//testmenu.visible=false;

}
