The problem of Emacs Muse subdirectories

[Water Lin]

According to examples in Emacs Muse package, I write following code to
set my Muse project and make it publish subdirectories:
--------------
(setq muse-project-alist
      `(
       ("TechWiki" (,@(muse-project-alist-dirs "~/public_html/MyWiki/wiki")
                 :default "index")
         ;; Publish this directory and its subdirectories.  Arguments
         ;; are as follows.  The above `muse-project-alist-dirs' part
         ;; is also needed.
         ;;   1. Source directory
         ;;   2. Output directory
         ;;   3. Publishing style
         ;;   remainder: Other things to put in every generated style
         ,@(muse-project-alist-styles "~/MyWebs/MyWiki/wiki"
                                      "~/public_html/MyWiki/wiki"
                                      "TechWiki"))))
--------------------------------------------

But when using C-c C-p to publish the project, Emacs reminds me
following warning:
------------------
No pages in TechWiki need publishing at this time.
------------------

I don't know why. I also set the style "TechWiki".

I think there is a minor mistake in my config file.

Thanks
