I see. You would have to add anchor links for each of the records based on the id and then you could add the anchor to the return url links as well.
So on the results page you might update this:
<td class="WADAResultsTableCell"><?php echo($WADAbucBuckets->getColumnVal("buc_id")); ?></td>
to:
<td class="WADAResultsTableCell"><a name="rec-<?php echo($WADAbucBuckets->getColumnVal("buc_id")); ?>"></a><?php echo($WADAbucBuckets->getColumnVal("buc_id")); ?></td>
And then on the details page update:
<input type="button" value="Back To Results" class="formButton unstyled" id="BackToResults" name="BackToResults" onclick="document.location.href = 'buckets_results.php<?php echo(isset($_GET["pageNum_WADAbucBuckets"])?"?pageNum_WADAbucBuckets=".intval($_GET["pageNum_WADAbucBuckets"]):""); ?>';" />
to:
<input type="button" value="Back To Results" class="formButton unstyled" id="BackToResults" name="BackToResults" onclick="document.location.href = 'buckets_results.php<?php echo(isset($_GET["pageNum_WADAbucBuckets"])?"?pageNum_WADAbucBuckets=".intval($_GET["pageNum_WADAbucBuckets"]):""); ?>#rec-<?php echo($WADAbucBuckets_details->getColumnVal("buc_id")); ?>';" />
