pagination displaying same results for all links

[reddyink]

Marco,
$page is loaded in the link with page=$page. In url of page when I click on on page it is showing proper link like page.php?page=2, but the results are same as page 1. Do I need to get $page values before the link. I have like this
for($page = 1; $page <= $maxPage; $page++)
{
if ($page == $pageNum)
{
$nav .= " $page "; // no need to create a link to current page
}
else
{
$nav .= " <a href=\"$self?page=$page\">$page</a> ";
}
}

In template I just call $nav. $nav is displaying correctly with links and page numbers. but results are same
<tr>
<div border="1" align="$stylevar[right]" style="padding-bottom:2px">$nav </div>

$usercategories - This variable has results
</tr>

Any suggestions are appreciated.
Thanks
