Have you already fixed this? I tested the page and it seems to be working correctly.
I see... I had to browse to the second page of results to see the issue.
I think you can just remove this code on line 159 of the results page:
<?php echo(isset($_GET["pageNum_WADAbucBuckets"])?"&pageNum_WADAbucBuckets=".intval($_GET["pageNum_WADAbucBuckets"]):""); ?>
Technically I think that code should be part of the link instead of displayed. So this:
<a href="buckets_detail.php?buc_id=<?php echo($WADAbucBuckets->getColumnVal("buc_id")); ?>" ><?php echo(isset($_GET["pageNum_WADAbucBuckets"])?"&pageNum_WADAbucBuckets=".intval($_GET["pageNum_WADAbucBuckets"]):""); ?>
<?php echo($WADAbucBuckets->getColumnVal("buc_name")); ?></a>
Should be:
<a href="buckets_detail.php?buc_id=<?php echo($WADAbucBuckets->getColumnVal("buc_id")); ?><?php echo(isset($_GET["pageNum_WADAbucBuckets"])?"&pageNum_WADAbucBuckets=".intval($_GET["pageNum_WADAbucBuckets"]):""); ?>" >
<?php echo($WADAbucBuckets->getColumnVal("buc_name")); ?></a>
