Assinging values to buttons

Hi there,

I have this piece of code:

bt_mc.addEventListener(MouseEvent.CLICK, onClick);
bt2_mc.addEventListener(MouseEvent.CLICK, onClick2);

function onClick(Event:MouseEvent):void {
function onClick2(Event:MouseEvent):void {

The thing that is crushing my skull is i have 6 buttons in each page and each one of them call a different movie. Is there a better way to call them, i mean, like, assign a value to each button so i dont have to write 6 different versions of the same function on my code?

any help really appreciated,
