rollOver issue

I’m modding a template for a friend, the site is pgaloans.com

When you go to the first page or the last page, everything works fine. The menu also corresponds to the current page by having the button remaining highlighted. However this isn’t working for pages 2 - 5, any idea why?

on (rollOver) {
    if (_root.link<>4) {
        this.gotoAndPlay("s1");
    }
}
on (releaseOutside, rollOut) {
    if (_root.link<>4) {
        this.gotoAndPlay("s2");
    }
}
on (release) {
    if (_root.link<>4) {
        _root["item"+_root.link].gotoAndPlay("s2");
        _root.link = 4;
        getURL("about.html");
    }
}

The actionscript is the same for every button, except the get URL and the _root.link=4 do change to the appropriate url/number.
