Flash :: Actionscript 3.0 Navigation Working On Home Page Only?

I am using the following code for my Navigation in a FLash CS4 file:

stop ();
function buttons(event:MouseEvent):void{
gotoAndStop(event.target.name);
}
home.addEventListener(MouseEvent.CLICK,buttons);
services.addEventListener(MouseEvent.CLICK,buttons);
about.addEventListener(MouseEvent.CLICK,buttons);
contact.addEventListener(MouseEvent.CLICK,buttons);

It works great when I am on the home page, but stops working once I navigate to any of the other pages. I have an Actions layer and that layer extends the full length of all pages/frames of the timeline.

I have the frames labeled as such: home, services, about, and contact. (All are "Type:Name")

each button is named as such: home/ instance of "home", services/instance of "services", etc.
