I need to get my users to enter two addresses, each required. How do I enforce unique responses through validation?
I am not sure if there is a built in validation tool to do this. You might be able to create this using the Scripting Resources: https://script.surveygizmo.com/help
If you don’t have a coder on your team then Surveygizmo does have programming services. https://www.surveygizmo.com/programming-services/
