The target column apparently can't be a named column, although the documentation could be more clear. > | ! | what | pw | ph | rp | ew | eh | re | f | > | | current | 720 | 1152 | 0.625 | 71 | 23 | 3.1 | 0.51612903 | > #+TBLFM: $5=$pw/$ph You need to put a recalculation mark into the first column (either "#" or "*"). > C-c ' > > Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil) > org-edit-src-code() > org-edit-special() > call-interactively(org-edit-special nil nil) What version of Org is this?
