[Orgmode] error in org-remember

[Xin Shi]

Hello Experts,

I recently update my Emacs to 23.1 and the org-mode to 6.30e.  Then I noticed my org-remember is not working. When I type C-c C-c, I got the following error: 

"Target files for notes must be in Org-mode if not filing to top/bottom"

My settings are:

(org-remember-insinuate)
(setq sx-notes-file-name "~/.notes.org")
(setq sx-journal-file-name "~/.journal.org")
(setq org-remember-templates
      '(
        ("Journal" ?j "* %U %?\n\n  %i\n  %a" sx-journal-file-name)
        ("Notes" ?n "* %^{Title}\n  %i\n  %a" sx-notes-file-name "Notes")
    )
      )
Any suggestions? 

Thanks!
Xin
