We were having an issue with the "Zone" field not being selected properly by the customer.
For example we had a default Country of the United States and therefore a default state/zone of "Alabama", however customers continually were not changing the selection of the zone and so their address would say that they were in Alabama.
So we created a blank zone name and set that to default, so that people would select their proper state in the address field.
However now, we get a lot of customers not filling in anything for the state and even though the field is marked as Required, it still lets a blank value come through.
Is there any way to make it so the form will validate the state field to make it so a blank value doesn't come through if the customer forgets to change their zone/state to the correct one on the form?
