Page navigation

I'm using the actionscript 3.0 to goto and play frame 30 which is what my products page is on, only problem is when I want it to go to frame 25 where my home page is, it says I have a duplicate function. Help?

Here's the code I used.
stop();
productbtn.addEventListener(MouseEvent.CLICK, release);
function release(evt:MouseEvent):void {
gotoAndPlay(31);
}

homebtn.addEventListener(MouseEvent.CLICK, release);
function release(evt:MouseEvent):void {
gotoAndPlay(25);
}

Here's the error:
1021: Duplicate function definition.
function release(evt:MouseEvent):void {

EDIT: Wow... I've been so overwhelmed with complicated stuff, that I was looking for a complicated answer. I tried something simple and it worked. Thanks for the help anyway guys.
