Hi!
In the customers loginform I don´t need the Telephon but their membershipsnumber, so I changed that text. This number is only five digits. Everything works, on the login, but on invoice and customer e-mail you still can see the word Telephone. What more shell I change?

Yes , everything is working fine. Thank You.
