I upgraded to tramp 2.1.9, and invoked the following code:

(require 'tramp)

(defvar tramp-db-num-prompt-regexp (concat (regexp-opt '("Please enter
your choice:") t) "\\s-*")
  "Custom regexp for interacting with the database number prompt at DS
Waters.")

(defun tramp-action-db-num-prompt (proc vec)
  "Enter \"0\" in order to choose a correct database."
  (save-window-excursion
    (with-current-buffer (tramp-get-connection-buffer vec)
      (tramp-message vec 6 "\n%s" (buffer-string))
      (tramp-send-string vec "0"))))

(add-to-list 'tramp-actions-before-shell
	     '((tramp-db-num-prompt-regexp tramp-action-db-num-prompt)))

When I tried using tramp, I got the following error:

Wrong type argument: symbolp, (tramp-db-num-prompt-regexp tramp-action-
db-num-prompt)

Thanks Michael.
