I am re-sending because I didn't include everyone on the original message.

Hi Nicolas Goaziou,

Thanks very much for your clarification:

hline relative references are not allowed on the left hand side of a formula

My error message was user-error: Can't assign to hline relative reference, which now makes sense. Still, a lot of folks didn’t understand the original message, myself included. I will update my SO post and the Github issue to reflect this new information.

Still, I am confused because it seems like org-mode used to allow hline references to be assigned, no? My code snippet was taken from a section in the timesheet.el MELPA package, which was working fine until an org-mode update broke it. I may be missing something, so I am not sure if this is the case.

Anyway, your response is very much appreciated!

Thanks,

Luke

This is a known limitation: hline relative references are not allowed on
the left hand side of a formula. The error message you get should be
explicit.

There are apparently subtle problems, IIRC, as pointed out in
<http://comments.gmane.org/gmane.emacs.orgmode/86960>.
