Changing button link

Hi,

I have a movie clip which directs to a different part of the flash movie.

I want to replace it to open an external link, but can’t make it work for some reason…

the code is:

onClipEvent (load) {
num = 7;
this.hitArea = this.area;
this.title1.gotoAndStop(num);
this.title2.gotoAndStop(num);
this.sq1.gotoAndStop(num);
this.sq2.gotoAndStop(num);
}
on (rollOver) {

    this.gotoAndPlay("s1");

}
on (releaseOutside, rollOut) {

    this.gotoAndPlay("s2");

}
on (release) {
if (_root.link<>num and _root.animation == 1 and _root.pressed == 0) {
this.gotoAndPlay(“s3”);
_root.pressed = 1;
_root.animation = 0;
_root.link_prev = _root.link;
//_parent[“item”+_root.link].gotoAndPlay(“s2”);
}
}

what exactly should i change?

Thanks,
Tom
