pagination displaying same results for all links

[reddyink]

Thanks for your effort. I changed code to empty. But no change. Still displaying same results for all pages.
I changed in query also to
$query = "select forum.*
,user.* FROM forum AS forum
LEFT JOIN user AS user ON (forum.userid = user.userid) where user.usergroupid='6' order by forum.forumid DESC LIMIT " . ($limitlower - 1) . ", $limit";

Any other suggestions
Thanks
