How can I specify a specific numeric key code to unlock a door?

Here is what I would like it to look like.

This door requires a security code to enter.
<if player has code, then display "Please enter security code">
"1234"
The door is now unlocked.
<if player does not have code, then display "I don't know any codes. Perhaps I can search the computers for help.">

hihoo,
i added a small tutorial to the wiki:

Oh, you are fantastic!!! Thank you!

Alright, I entered the components, but I cannot unlock the door. What does the player need to type to unlock the door (i.e., the use option is unavailable on the keypad... now what?)?

I was able to make it work under the verbs tab using "enter code on" as the verb to the keypad. I gave flavor text to help the user with this since "use" keypad is not working for some reason.

But the keycode works wonderfully now.
