hi to all. i’m new to the forum and to as3 and I would really appreciate some help. why does this not work?

```auto
 var menuArr:Array = [home_mc, menu1_mc, menu2_mc];

```

when I iterate with a for loop to add event listeners

```auto
var i:uint;
   for (i=0; i<menuArr.length; i++)
   {    
       menuArr*.addEventListener(MouseEvent.CLICK, GO);
       menuArr*.addEventListener(MouseEvent.MOUSE_OVER, menuOver);
       menuArr*.addEventListener(MouseEvent.MOUSE_OUT, menuOut);
       menuArr*.buttonMode = true;
}

```

flash says:

> TypeError: Error #1009: Cannot access a property or method of a null object reference.  
> at main()

EDIT: Please note that the below syntax works!!:

```auto
menuArr[0] = home_mc; 
menuArr[1] = menu1_mc; 
menuArr[2] = menu2_mc;

```

thank you for your help.
