I don't see the code I told you to add... it should be right after this:
<?php for($i=1;$i<=3;$i++) { ?>
<?php
mysql_data_seek($rsProductUpdates, $i);
$row_rsProductUpdates = mysql_fetch_assoc($rsProductUpdates);
?>
<?php if ($row_rsProductUpdates) { ?>
and then close it right when you close the for loop like:
<hr>
<?php } // I added this ?>
<?php } // Show if recordset empty ?>
