Hi,

I am having trouble passing an additional value through the addEventListener method. Can someone tell me how to pass in values so my function knows what buttons were pressed?

a.addEventListener(MouseEvent.MOUSE\_UP, jumpThumb(“mouseUp”, 0));  
b.addEventListener(MouseEvent.MOUSE\_UP, jumpThumb(“mouseUp”, 1));  
c.addEventListener(MouseEvent.MOUSE\_UP, jumpThumb(“mouseUp”, 2));

function jumpThumb(event:MouseEvent, mouseButton:int):void {  
//statement that uses value of mouseButton  
}

Thanks for any help!

Bobby

event.target will tell you what button was pressed…
