Button code - please help :(

Hi everyone.

is this code correct?

Code:

---

onClipEvent (load) {
        num = 3;
}
on (rollOver) {
        if (_root.link<>num) {
                this.gotoAndPlay("s1");
        }
}
on (releaseOutside, rollOut) {
        if (_root.link<>num) {
                this.gotoAndPlay("s2");
        }
}
on (release) {
        if (_root.link<>num) {
                _parent["but"+_root.link].gotoAndPlay("s2");
                _root.link = num;
  getURL("http://www.siborg.com/nina/public_html/core_practice.html","_self");
        }
}

---

Also, I was given these button template. But now its acting all wonk once the site leaves the root directory.

Only my navigation is in Flash, my site is in HTML.
