Template Button Problem

Hi, Hi hope this is the right subject to be posting under and that someone with a bit more knowledge than me can help!

I bought a template which has this bit of code attached to each button:

on (rollOver) {
b1.play();
}
on (release) {
_root.dog.play();
// loadMovieNum(“hugo87_1.swf”,2);
if (_root.pressed_link<>2) {
_level2.gotoAndPlay(“dissappear”);
_root.pressed_link = 2;
}
}

My stumbling block is the fact taht i can’t seem to expand on the web site to make any extra links which open up on the same page. I can easly create links which link off to other sites but obviously to make it right i need to enable navigation around the actual site.

If anyone could give me an explanation of the above snippet of code i’d be very grateful.

Thanks
Roy
