This is very different than tickets.inc.php. I was able to add a new column to the User Directory page table (users.inc.php), however, I was unable to get the sort function to work. When clicking on the header "Company", the table data disappears. Adding new column "Company": (new field in "Contact Infomation Form")-----------------------------------------------------------$users->values('id', 'name', 'default_email__address', 'account__id','cdata__company',    'account__status', 'created', 'updated');----------------------------------            <th><a <?php echo Company; ?> href="users.php?<?php                echo $qstr; ?>&sort=company"><?php echo __('Company'); ?></a></th>----------------------------------<td class="nohover" align="left"><?php echo $U; ?></td>
