newbie. skeleton question.

[Pawel]

I defined simple skeleton:

(define-skeleton sexpr-example
  "Insert a silly example."
  ""
  > "Emacs version is: " emacs-version \n
  > "And time is: " (current-time-string))

(define-abbrev text-mode-abbrev-table "slly" 
   "silly text: " 'sexpr-example)

M-x sexpr-example : works for me.

while,
slly<SPC> does not. I am of course in buffer with text-mode.

Have You got idea, why?

Regards,
Pawel
