Hey folks,

I need to call the function onClick before or after the eventListener is enabled. I tried just using onClick(); but I get error 1136: Incorrect number if arguments.

The eventListener is inside a for loop if that matters.

```auto
 
onClick();
 
for(var i:int = 0; < labelArray.length; i++){
typeButtonBack.addEventListener(MouseEvent.CLICK, onClick);
 }
function onClick(event:MouseEvent):void {
  Do something();
}

```

Thanks for the help

Jason
