I have done this and still showing failure upon 'override

(defvar elisp-hglevels

     (";;; H5" . 5) (";;; H6" . 6) (";;; H7" . 7) (";;; H8" . 8) ))

(defun outlhg-regexp ()

  (cond
    ((eq major-mode 'emacs-lisp-mode)
          (let ( (hrklevels elisp-hrklevels) )
            (setq outline-regexp
                  (concat (regexp-opt (mapcar 'car hrklevels)) "\\>"))
            (setq outline-heading-alist hrklevels))) ))
