haven't tried it, but in theory this should work. find this file: /includes/classes/order.php
and using 'firstname' as an example field, search through the document and every instance of 'firstname', copy and paste that line, then add your variable.


@jahmar
Sounds like there may be something missing in /includes/modules/pages/account_edit/header_php.php
Do a search for 'extrafield' and make sure there is an instance for extrafield2 and extrafield3 in every single place that the other one is.
