Is there a way to use logic to block out days?

Great! Is there a way to use logic to block out days that have already been taken by someone in a different zip code? We drive out to our appointments and want to keep from having to drive from one part of town to another on the same day due to the gas and time expense.

I am afraid this is not currently possible o limit the appointments based on zip codes and data from other fields. You may consider submitting feedback to our developers via the Appointment field, so there is a chance that something like this will be implemented in the future.
