Passing variables from eventListener to function AS3

hey guys,

I am stuck in AS3

I got a function with For loop… that created instances of a button… … now when i press one of these buttons i want to load up an image… so i used the code below to call the function when you click on the menu item.

portMenu.addEventListener(MouseEvent.CLICK, displayPort);

the for loop also includes var Title:String = mainXML…item*…IMAGE.text();

then here is the function that gets called when the button is pressed…

function displayPort(event:MouseEvent){
	 var ldr:Loader = new Loader();
	 var urlReq:URLRequest = new URLRequest("   I WANT TO INSERT IMAGE VALUE HERE    ");
	 ldr.load(urlReq);
	 displayMC.addChild(ldr); 
	 ldr.x = 20;
	 ldr.y = 100;
}

can anyone help thanks
