Multiple instances of Movieclips working with AS3

Here is what i would like to do. I have Multiple movieclips that when you hover over, a info box pops up and stays active until the mouse is moved away from the info box. Simple enough. I have multiple movieclips and i cannot get more than one to work. In order for the movieclip to work the instance name is ‘mc’ and this is the code i am using:

mc.addEventListener(MouseEvent.ROLL_OVER, overHandler);
function overHandler(evt:MouseEvent):void {

mc.addEventListener(MouseEvent.ROLL_OUT, outHandler);
function outHandler(evt:MouseEvent):void {

I have tried duplicating the text and changing it to ‘mc1’ to match the instance name of my other movieclip and get a duplicate error on the ‘function…’ line. When i preview only the ‘mc’ instance works.

What am i doing wrong?
