I tried changing the telephone filed into USER NAME since I needed it the most thant the telephone, but, the problem is how do i change it here? Since it doesn't record on this page.
That page is this file: /include/staff/viewticket.inc.php. You'll need to change the variable.
<tr>
<th>Phone:</th>
<td><?=Format:($ticket->getPhoneNumber())?></td>
</tr>
