I am having a problem getting this to work. I get this error:

**TypeError: Error #1010: A term is undefined and has no properties.**

It is because of the line of code in bold. It doesn’t like the **this[NavName].** Any suggestions?

for(var i:Number=0; i\<11; i++)  
{  
var num:Number = i;  
var NavName:String = “Nav” + num;  
\*\* this[NavName].addEventListener(MouseEvent.CLICK, runNav);  
\*\*  
function runNav(event:Event):void  
{  
trace(“hello”);  
dispatchEvent(new changeNav(num))  
}  
}

Cheers!
