Passing user selection to a command

[Heime]

How can I pass the user selection to 'activate-input-method' ?


(defun glossus ()

  (interactive
   (list
    (let ( (cseq '("italian-alt-postfix" "italian-keyboard"
                     "italian-postfix")) )
      (completing-read
        " Glossus: " cseq nil t "italian-postfix"))))

  (setq ispell-local-dictionary "it_IT")
  (activate-input-method "italian-postfix") )
