What is wrong with this method?

[tjohnson@magnus.acs.ohio-state.edu (Todd R Johnson)]

What is wrong with this method and what does this error mean? I've
read about the error message, but the error still doesn't tell me what
is wrong.

The method:

(in-package :Action)

(defclass score (ApplicationEdit) ())

; Initialize the application
; Compute and print the game number, current round score and total
score.
(defmethod initialize ((score Score) blackbox &aux foo)
  (set-namedobject score :gamenum (gamenum blackbox))
  (set-namedobject score :score (score blackbox))
  (set-namedobject score :total (total blackbox)))

The error:

> Error: Incompatible lambda list in #<STANDARD-METHOD INITIALIZE
(SCORE T)> for #<Compiled Generic-function INITIALIZE #xA3A00E>
> While executing: CCL::CHECK-DEFMETHOD-CONGRUENCY
> Type Command-/ to continue, Command-. to abort.
> If continued: Remove 32 methods from the generic-function and fix
its lambda list.
See the RestartsI menu item for further choices.

I'm using Action with MCL and I am supposed to be able to include
additional arguments in the initialize method. I had this problem once
before with a method, but after quiting MCL and reloading, the error
went away.

I can get rid of the error by removing the "blackbox" parameter, but I
really need that parameter.
