Hi,

I am trying to add to my refile target list a file that exists in a
sub-directory of org-directory. I have tried to do this by concatenating
 the variable org-directory with the string containing the path to the file
like so:

(setq org-refile-targets '((nil :maxlevel . 9)
                           (org-agenda-files :maxlevel . 9)
                           (concat org-directory "/projects/project.org"
:maxlevel . 9)))

This does not seem the right way to do it as I get the error
org-refile-get-targets:
Bad refiling target description (org-directory
/projects/project.org:maxlevel . 9)when I try to refile something.
Unfortunately I do not have sufficient
knowledge about elisp to correct this, but I am willing to read-up if
pointed in the right direction. Any suggestions are welcome.

Thank you.
