How do i Put a URL link in this button?

yeh i know its dumb but I bought something off of flashden.net.. and i'm confused about putting a link in the code.. ITs probably so simple. its just a scrolling list for navigation... but it has dummy items.. When i went to add my own lists to it, it so weird. Heres what it looks like

//------------------------------------------------
//total menu items
ti = 10;
//------------------------------------------------
//set up some demo items
n = 0;
while (Number(n)<Number(ti)) {
set("item" add n, "item" add n);
n = Number(n)+1;
}
//------------------------------------------------
//what to do with YOURs?
//remove the above LOOP (which creates dummy variable names.) START at "0"!!!!! Create variables named item0="blah", item1="test", item2="and so on..." and you're set! Look at the button action. It is currently set to GETURL and load a "swf" file with the same name as the button you just clicked on into a placeholder (which does not exist in this demo).

So what do i do to add a link to say "contact" that goes to a url?

thanks any help is greatly appreciated!
