[otrs] adding customer last names to responses

Hi, In my salutations, I would like to say the German equivalent of "Dear Mr. [lastname]" and have the lastname automatically inserted. It doesn't seem to be reading the last name when I use the option . Is this wrong? Procedure that I'm using: - Setup signature with body "Sehr geehrter Herr " - Reply to message (for example a message from: 'Tabitha Stang' stang@cb.com) As a result, I get "Sehr geehrter Herr -," when it should say "Sehr geehrter Herr Stang". How do I fix this? Thanks so much! Tabitha
