like Ian had posted before, the fix is to change:
<td><?php echo $row_rs_job['url']; ?></td>
to:
<td><a href="http://<?php echo $row_rs_job['url']; ?>"><?php echo $row_rs_job['url']; ?></a></td>
it does not look like you have tried to implement this on the page you have linked to. What I was asking for was a page that you have tried to implement the code on where it is not working.
