Validation rule on City field in Address

Hi,

Is there a way to restrict the options for the City field inside of an address block?  We only want people who fill our form out to be from a particular city, but also don't want to hide the field, since we want them to visibly see that they need to be entering this particular city.

This is the result:

You can add the following conditions: 

My recommendation is to clone the form and test it: How-to-Clone-an-Existing-Form-from-a-URL.

If you need any further assistance, please let us know. We will be happy to help.
