Redirect to url – default value

Thanks in advance! I have created a Formidable field to find a conference room by submitting the room number. I used redirect to url to send people to the page of the conference room number they submit. It works like this:

http://[if 112 equals=”201″]mysite.com/201-2/[/if 112][if 112 equals=”202″]mysite.com/202-2/[/if 112]

But if the site visitor submits a room number that doesn’t exist, nothing happens. How do I set up a “default” submit to url address to send room numbers not included in the code to all go to a specific page?

Thanks again.
