Good Day, I am encountering clocktable :step errors with EMACS. The following command M-x org-clock-report applied to #+BEGIN: clocktable :maxlevel 4 :scope tree2 :tstart "<2021-10-03 Sun 00:01>" :tend "" :step month :narrow 75! :link nil #+END: clocktable yields the following error message Wrong type argument: number-or-marker-p, nil The same error occurs with :step semimonth and :step year as well. If I use :step day or :step week, there is no error and EMACS cheerfully produces the desired report. Online documentation states the :step month, semimonth or year commands are valid. The below link is one such instance. https://www.gnu.org/software/emacs/manual/html_node/org/The-clock-table.html But, I have tried the :step commands with Emacs 25.3.1 on Windows 10, Emacs 26.3 on Windows XP and Emacs 26.3 on my Android phone through Termux. All three versions do not accept the :step month, :step semimonth or :step year command. I have concluded the :step month, semimonth or year commands were valid at one time and online documentation has not caught up with the change. It is not a big problem, but É thought worth bringing to your attention. Regards, Craig Smith Texas
