Hi Bart, You've mixed up #+call and sbe there. sbe is what you want to use in a table formula; #+call and #+lob are for standalone lines. Here are a few examples of different ways to do what you're doing. Hopefully they make things clear. Dan --8<---------------cut here---------------start------------->8--- * Totals ** Using a table formula *** Relying on default argument to totals block | Total | 155 | #+TBLFM: $2='(sbe "totals") *** Providing argument explicitly The dots are a bug. We'll fix it. **** version 1 | Total | 155... | #+TBLFM: $2='(sbe "totals(details=expenses[1:-1])") **** version 2 | Total | 155... | #+TBLFM: $2='(sbe "totals" (details "expenses[1:-1]")) ** Using call/lob #+call and #+lob are synonyms *** Relying on default argument to totals block #+call: totals() #+results: totals() : 155 or equivalently (it outputs into the same results block): #+lob: totals() *** Providing argument explicitly #+call: totals(details=expenses[1:-1]) #+results: totals(details=expenses[1:-1]) : 155 --8<---------------cut here---------------end--------------->8--- > > _______________________________________________ > Emacs-orgmode mailing list > Please use `Reply All' to send replies to the list. > Emacs-orgmode@gnu.org > http://lists.gnu.org/mailman/listinfo/emacs-orgmode _______________________________________________ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.
