The following example shows that the accumulative property isn't restricted to var/var+. * Accumulative properties syntax #+property: not-var 0 :PROPERTIES: :not-var+: 3 :END: #+begin_src emacs-lisp (org-entry-get (point) "not-var" t) #+end_src #+results: : 0 3 To run the example, you'll need to refresh the local setup by C-c C-c on the #+property: not-var 0 line, then execute the emacs-lisp source block. I didn't follow this thread closely, so I don't know if my experience is useful, but when I briefly studied the accumulative property syntax I tripped up on two things: 1) I often forgot to renew the local setup so that changes in #+property: lines would take effect; and 2) I tried to add more than one instance of a property in a drawer, which isn't allowed. hth, Tom -- Thomas S.
