Thanks for the great session. I love the calculate fields based on the location.
Can you make a location field answer a yes/no question and only show further questions in the survey if the answer was yes?
E.g. ask for an Address/location. If the address is in your government area, question 2 says yes and therefore the person can complete questions 3 and so on. If it is not in your government area, question 2 says no and they cannot submit any further answers.
I think this might be currently limited because while you can calculate a location into a dropdown, it doesn't support a default choice, and also no rule can be applied to choices in the designer.
