accordion menu error 1010

Question

I'm trying to create an accordion menu off of an online tutorial. I followed every step (i think) on Original Tutorial but changed things according to my size, as well as make the instance names end with _mc or _txt accordingly. But for some reason it doesn't seem to be working.

I'm getting the #1010 error and it doesn't really clarify anything:

TypeError: Error #1010: A term is undefined and has no properties.
at tutorial_fla::MainTimeline/placeItemsOnStage()
at tutorial_fla::MainTimeline/onComplete()
at flash.events::EventDispatcher/dispatchEventFunction()
at flash.events::EventDispatcher/dispatchEvent()
at flash.net::URLLoader/onComplete()

I have my first xml file that has all the images to insert and that one hasn't been changed at all should work fine.

I know this is long, but I'm hoping someone can check it out anyhow. I'm extremely new to this and would pretty much have to abandon the whole project. Thanks so much!

my code:

//import tweenlite classes
import gs.TweenLite;
import gs.easing.*;

var MENU_ARRAY:Array; //used to save the items data
var OPENED_MENU:int; //to inform the menu that should be open at startup
var MOVE_ON_MOUSE_OVER:Boolean=false; //tha name says everything
var xmlLoader:URLLoader; //the xml loader

loadXML("menu2.xml"); //load the xml

function loadXML(Uri:String):void {
   xmlLoader = new URLLoader();
   xmlLoader.addEventListener(Event.COMPLETE, onComplete);
   xmlLoader.addEventListener(IOErrorEvent.IO_ERROR, onError);
   xmlLoader.load(new URLRequest(Uri));
}

function onError(evt:ErrorEvent):void {
   trace("cannot load xml file");
}

function onComplete(evt:Event):void {
   //read and load xml into array, by parsing it using prepareMenu
   MENU_ARRAY=prepareMenu(xmlLoader.data.toString());
   placeItemsOnStage(); //place all required items on stage.
}

function placeItemsOnStage():void {
var pos:Number=0;
    //define the container properties
    menuContainer_mc.x=0;
    menuContainer_mc.y=0;

for(var c:int=0; c<MENU_ARRAY.length; c++) {
  var it:menuItem = new menuItem; //load out menuItem, because its exported to AS, we can use it here
    it.x=c*51; //its the gray border width
    it.y=0; //place on top
    it.id="Item-"+c; //id the menuItem
    it.name="Item-"+c; //name de menuItem
    it.posX=pos; //actual pos, useful to open and know is position
    it.itemLabel_txt.text=String(MENU_ARRAY[c].Ititle).toUpperCase(); //load the label in uppercase
    it.addEventListener(MouseEvent.CLICK, onMouseClick); //add mouse click listener

//put mask in place

     if(tempMc.x > itemToMove.x) TweenLite.to(tempMc, 1, {x:((tempMc.posX) + itemToMove.width-51), ease:Quart.easeOut}); //see tweenLite for info about this.
     else if(tempMc.x <= itemToMove.x) TweenLite.to(tempMc, 1, {x:(tempMc.posX), ease:Quart.easeOut});
   }
 }

 function prepareMenu (XMLData:String):Array
   {
  //make sure it cames in XML
  var menuXML:XML = new XML(XMLData);
  //just in case
  menuXML.ignoreWhitespace = true;

  //get XML item's entrys
 var XMLItems = menuXML.descendants("item");

  //load all items into an array
  var itemsArray:Array = new Array();
  var itemObj:Object;
  for(var i in XMLItems)

  }
  OPENED_MENU=menuXML.@menuOpen; //get menu for open.
  MOVE_ON_MOUSE_OVER=([email protected]()=="true" ? true : false); //get the option for load or not mouseOver open
  return itemsArray;
}

//finish.
stop();

"term" refers to an identifier, "Error #1010: A term is undefined and has no properties" means you are using an expression which cannot be evaluated. This usually happens when you try to access and use an undefined object property via its string name as in myobject["property"].method(). Can you provide the exact line on which the exception is raised?
