        $offsetValue="";
        $previousurl="";
        $nexturl="";

// offset is used as a token which used to limit the no. of friends
        if(isset($_GET["offset"]) && is_numeric($_GET["offset"]))
        {
            $offsetValue="&offset=".$_GET["offset"];
        }
// limit the friends according to  the offset

        $friends = $facebook->api("/me/friends?limit=".$friendsPerPage.$offsetValue);


        if(isset($friends["paging"]["next"]))
        {
            $nexturlOffset = returnFbOffset($friends["paging"]["next"]);
            $nexturl = "Next »";
        }
        if(isset($friends["paging"]["previous"]))

function returnFbOffset($url)
