[otrs] Services in Ticket Templates

Hi All, Did anybody manage to automatically select Services in Ticket Templates? I tried setting it up in using both http://blog.otrs.org/2010/11/02/otrs-3-0-ticket-templates/ and TicketTemplate-0.1.94 module from OPAR but no luck (the dropdown box is empty until I select the customer). This is one of the last few things I need to sort out before we go live with OTRS so many thanks for any help J OTRS 3.0.6 with ITSM 3.0. - Robert
