you will need to chnage the value="4" for each class e.g (admin,sysop,mod)

if you open include/global.php and serach for define ('UC_ ) you will have a list like below :

define ('UC_USER', 0);
define ('UC_POWER_USER', 16);
define ('UC_VIP', 32);
define ('UC_BOT', 33);
define ('UC_SUPER_VIP', 34);
define ('UC_UPLOADER', 48);

you will need to match the end numbers to your staffmess.php so it looks like this

  <td style="border: 0" width="20"><input type="checkbox" name="clases[]" value="0">
             </td>
             <td style="border: 0">User</td>

             <td style="border: 0" width="20"><input type="checkbox" name="clases[]" value="16">
             </td>
             <td style="border: 0">Power User</td>
             
             <td style="border: 0" width="20"><input type="checkbox" name="clases[]" value="22">
             </td>
             <td style="border: 0">VIP</td>

Hope that helps
