elisp errors

[synhedionn]

hi,
I try to evaluate, for doing indentation of poub.y(so C-mode):
(defun indentTabs()
 (interactive)
  (   save-excursion ; cf
http://www.cs.tut.fi/lintula/manual/elisp/emacs-lisp-intro-1.05/emacs-lisp-intro_13.html#SEC145
restores point to its original position
    (   message "coucou"   )
    (goto-char (point-min))
(let  ((cpt 100))    ;double parenthese obligee
    (while (> cpt 0)
      (
    ((c-indent-command));   widget-forward                      ;TAB
      ( move-beginning-of-line 0)
     (  next-line 1)

        (setq cpt   (1- cpt)) ;  (1- cpt))
; ( message "cpt=%d"( 3 )  );!! parentheses autour cpt
           (   message "fin partielle"   )
              )) )  ) )

I do C-x C-e at end of command
Then , in my poub.y : M-x indentTabs
But error: Invalid read syntax: expected lambda expression (((c-indent-
command));   widget-forward                     ;TAB    )
What does it mean(evaluate by own your correction suggestion, please)?
