Using button to display a help menu

[Heime]

Have made a function called 'maces' that is intended to show a button called 
'Organis'
to display a help page as defined in 'maces-organis'.  Although I get the 
button 'Organis',
when I press it, I get 

--------

(wrong-number-of-arguments ((t) nil "Prints information about Maces Organis." 
(interactive) (help--window-setup (help-buffer) #'(lambda nil (insert-button 
"[F7]" 'action 'maces-action-organis 'follow-link t) (insert " Maces Organis 
\n")))) 1) maces-organis(#<overlay from 72 to 76 in *Help*>)

--------

(defun maces-organis  ()
  "Prints information about Maces Organis."
  (interactive)

  (with-help-window (help-buffer)
    (insert-button "[F7]" 'action 'maces-action-organis 'follow-link t)
    (insert " Maces Organis \n") ))


(defun maces ()
  "Prints information about Maces."
  (interactive)

  (with-help-window (help-buffer)
    (insert-button "[Organis]" 'action 'maces-organis 'follow-link t)
    (insert " Maces Organis \n") ))
