Hi,
I have added custom todo keywords. I am unable to get any agenda view except
for timeline (C-c aL).
All other search for tags (C-c am) todo(C-c at) show empty agenda buffer.
Any solutions.
Here is my configuration.
I am using ntemacs -  23.0.0.1.
Org-mode - 5.21
and my org specific section is as follows.

;

;; The following lines are always needed.  Choose your own keys.
(add-to-list 'auto-mode-alist '("\\.org$" . org-mode))
(define-key global-map "\C-cl" 'org-store-link)
(define-key global-map "\C-ca" 'org-agenda)
(add-hook 'org-mode-hook 'turn-on-font-lock)  ; org-mode buffers only
(require 'org-install)
(setq org-agenda-include-diary t) ;add all diary entries to agenda view
; (setq org-log-done '(done)) - moved to individual file #+STARTUP:
lognotestate
(setq org-todo-keywords
           '((sequence "Project" "Started" "InProgress" "NearingCompletion"
"|" "Completed" )
             (sequence "Task" "Started" "|" "Completed")
             (sequence "NextAction" "|" "Completed")))
(defface org-project-face '((t (:foreground "blue" :weight bold :bold t)))
  "Face for Project todo items.")
(defface org-task-face '((t (:foreground "cyan" :weight bold :bold t)))
  "Face for Task todo items.")
(setq org-todo-keyword-faces
      '(("Project" . org-project-face)
        ("Task" . org-task-face)
        ("NextAction" . org-warning)))
(setq org-agenda-custom-commands
      '(("n" todo "NextAction")))
;; remember mode for Org
(require 'remember)
;;(org-remember-insinuate)
(setq org-directory "e:/Amol/Work/EmacsOrgDir/")
(setq org-default-notes-file (concat org-directory "/notes.org"))
(define-key global-map "\C-cr" 'org-remember)
;; templates for Org - remember
(setq org-remember-templates
      '(("Todo" ?t "* TODO %?\n  %i\n  %a" (concat org-directory
"/TODO.org") "Tasks")
       ("Journal" ?j "* %U %?\n\n  %i\n  %a" (concat org-directory
"/JOURNAL.org"))
       ("Idea" ?i "* %^{Title}\n  %i\n  %a" (concat org-directory
"/JOURNAL.org") "New Ideas")))
;

Thanks a lot.
