How come planner-cyclic can't work ?

Hello,everyone
I try to use planner-cyclic for my appointments ,but it can't work.I
customize planner-cyclic and planner-appt like this:
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

(require 'planner-appt)
(planner-appt-use-tasks-and-schedule)
(planner-appt-insinuate)
(require 'planner-cyclic)
(setq planner-cyclic-diary-file "~/.emacs.d/.diary")

(planner-appt-schedule-cyclic-insinuate)
(setq planner-appt-task-use-appointments-section-flag t)
(setq planner-appt-schedule-cyclic-behaviour 'future)
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

The content of diary looks like this:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Schedue
Monday @12:00 lunch
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Would anyone help me?
