[O] Using Variable in Org-capture configuration

[Chao LU]

Dear all,

Just writing to see if it is possible to use variable in org-capture configuration, like this

 (setq org-capture-templates
           '(("t" "Todo" entry (file "~/org/refile.org") "* TODO %?\n  %i\n  %a" :prepend t)))

                                              ------------------------
                                                       \---How could I use-> (concat My-Dropbox-Path "refile.org")

Since I put all my files in Dropbox, and the My-Dropbox-Path has different values under MAC and M$Windows.

Thanks,

Chao
