Page Rendering

Hi all. I am having some problems with a script which reads information from a database and creates a table. It works in IE but not Netscape. I call myself going through the tags to make sure all that were open were closed because Netscape doesn't like unfinished business. What I have is a script that outputs the previous page, 1, 2, ..., next page link (if there are more than x table items per page). It has worked in both browsers but now I have broke something. :o) Any ideas are appreciated. The code is like this ... <?php function pagelinks($prev_page, $num_pages, $next_page, $page) { // This displays the "Previous" link if ($prev_page) { echo "<a href=\"$PHP_SELF?page=$prev_page\">&lt;&nbsp;Prev</a>&nbsp;|&nbsp;"; } // No need to output the page number if there is only one page if ($num_pages>1) { for ($i = 1; $i <= $num_pages; $i++) { if ($i != $page) { echo " <a href=$PHP_SELF?page=$i>$i</a>"; } else { echo " $i "; } } } // Display the "Next" link. if ($page != $num_pages) { echo "&nbsp;|&nbsp;<a href=\"$PHP_SELF?page=$next_page\">&nbsp;Next&nbsp;&gt;</a>" ; } } ?> This code is at the top of an include file which is included in pics.php. It seems that $PHP_SELF is interpreted differently in *some* instances between the two browsers. I can't figure it out because PHP_SELF is a server side evaluation. The links are output correctly in IE ... http://www.xyz.com/pics.php?page=2 ... but in Netscape I get ... http://www.xyz.com/?page=2 I had this problem once before and inadvertently fixed it with something else that I was doing. Any hints are appreciated. TIA, Bill
