Premature call to a function

;;;;;;;;;; ... namespace stuff goes here

     (config! f :content content)

;;;;;;;;;  AFTER MANY DECLARATIONS...

;;;;MUCH LATER...

;;;;;;;;;;;;;;;;;;;;;;;;   ...TWO MORE JUST LIKE WHAT IS ABOVE THIS, THEN WRAPPING UP GUI STUFF

(defn -main [& args]
  (invoke-later
    (display (make-window))
    (-> f show!)))

;; The problem seems to be that the function armor-res-util gets executed before all of the id's it needs
;; get declared.  It shouldn't be executing at all until one of the slider's or combobox's selection events gets called!
