Hi everyone,

I have a function that I called from a Mouse click listener, shown below

```auto
btn_stop.addEventListener(MouseEvent.CLICK, stopVid, false, 0, true);

function stopVid(event:MouseEvent):void{
	VidComp.pause();
	VidComp.seek(0);
	showPlay();
	tmrDisplay.stop();
	resetTimes();
}

```

I want to call the stopVid function elsewhere, but I need to pass it a parameter. So this does not work:

```auto
stopVid();

```

So my question is is there an empty parameter I can pass or one that will work?

I’ve tried the following:  
event.Event  
event.Event = null  
null

Any responses will be greatly appreciated.
