Instance names in array?

1

I have a bunch of buttons on stage, and i want to place all of those buttons names in an array so i can assign an event listener to them easier. What i have is:

var btnArray = new Array["btn1","btn2","btn3","etc...."];

for(var c=0; c<btnArray.length; c++)
{
    btnArray[c].addEventListener(MouseEvent.MOUSE_OVER, doSomething);
}

But that isnt working. Is there a good way to go about this?

Thanks.
