I have a function that needs to be called when the mouse is moved over a button that has been attached to the stage. The function is called scrollZone. However, I need to pass scrollZone some parameters… but how? Whatever I do seems to result in a compile error.

```auto

btnDown.addEventListener(Event.MOUSE_OVER, scrollZone);

```

I want to be able to do something like this:

```auto

btnDown.addEventListener(Event.MOUSE_OVER, scrollZone(param1,param2,param3));

```

Can someone give me the correct syntax?

Thanks!
