Multiple Hyperlink Help

So I've fairly new to Flash (using CS4). I've been trying to put five different hyperlinks on the same stage, but I can't seem to get them all to function.

I used the AS3 code:

function init() {
button.addEventListener(MouseEvent.CLICK, WebHyperlink);
}
init();
function WebHyperlink(e:MouseEvent)
{
var button:URLRequest = new URLRequest("http://...");
navigateToURL(button, "_self");
}


I can only get this function to work with one link on the stage at a time. How would I be able to put more than one hyperlink at a time? Please help! THX
