Templates and custom field insertion

[handmadeza]

I am new to WHMCS and have 2 installations, which are working pretty well. The problem I am having is inserting custom fields into template files. Browsing through the forum I managed to find several questions related to this, however I need to insert custom fields into the admin template and not the front end templates.

 

I need to insert a custom field (Cell No.) into the ticket list table. According to what I have found is that the insert should be : $client_custom_field_cellnumber

 

I have obviously setup the custom fields in the applicable Support Departments and they are successfully being entered via the front end forms

 

I am not sure which template file for admin is applicable, but the url call is to supporttickets.php?view =active

 

Is this possible and if so which template file should I be inserting the variable into?

 

Thanks in advance
