[Orgmode] clocktable and :step

[Chris Randle]

Hi

Please could someone give me some examples of using :step with a
clocktable? I've tried all the arguments I could think of to see what
effect it has, but everything so far, except nil as an arg, gives the
error "Wrong type argument: number-or-marker-p, nil" after a C-c C-c.

Windows XP, Emacs 22.1.1, Org-mode 6.02
