Hello all,

rather a lisp newbie and been searching all over, but can't figure it out.
I have the code below:

(provide 'ian-project)
;; Based on the presence of the 'project' environment variable,
;; display the project name in the frame title and the mode line.
(defun set-project-in-frame-title ()
  (interactive)
  (setq projectname (getenv "project"))
  (message "Project: %s" projectname)
  (if projectname
      (setq-default frame-title-format (concat "%b (%*) [" projectname "]
"))
    (setq frame-title-format (concat "%b (%*)"))
    ) ;; if projectname
)

And in my ~/.emacs I have:

(require 'ian-project)
(set-project-in-frame-title)

The message "Project: <projectname>" is displayed in the *Messages* buffer
on startup, however, the project name does not end up in the frame title,
unless I execute the function by hand:
M-x set-project-in-frame-title()

My emacs version is:
GNU Emacs 24.2.1 (x86_64-redhat-linux-gnu, GTK+ Version 3.6.4)
 of 2013-02-02 on buildvm-04.phx2.fedoraproject.org

Thank you very much in advance for any pointers as to what I may be missing.

Ian.
