I still get the "Wrong type argument: numberp, (0.5)" error.

Here's the stacktrace for the error that I get when I set org-refile-targets
with the following code:


  ;; Use environment variable $ORGDIR to get dir for org-directory
  (setq org-directory (getenv "ORGDIR"))
  (setq notesmine-dir "~/Documents/notesmine-org")

  (setq org-agenda-files (file-expand-wildcards (concat org-directory
"/*.org")))
  (setq notesmine-files (file-expand-wildcards (concat notesmine-dir
"/*.org")))

  ; Targets include this file and any file contributing to the agenda - up
to 5 levels deep
  (setq org-refile-targets
   (quote
     (
       (org-agenda-files :maxlevel . 5)
       (notesmine-files :maxlevel . 5)
       (nil :maxlevel . 5)
     )
   )
  )
