Tiny bit of help

i’m pretty new to flash and as3, i’m a student in the process of learning a lot more about it.

that said, i have a simple movie clip animating that i want the user to be able to click different buttons to cycle through different versions of this movie clip.

so, my question is, how do i allow the user to click one of these 4 buttons, and have the movie clip change to the corresponding version of that movie clip?

again, this is all pretty basic stuff and i’d like to keep it as simple as possible, since i’m still new!

c1.addEventListener(MouseEvent.CLICK, hand1);
c2.addEventListener(MouseEvent.CLICK, hand2);
c3.addEventListener(MouseEvent.CLICK, hand3);
c4.addEventListener(MouseEvent.CLICK, hand4);

function hand1(evt:MouseEvent) {
what goes here??
