How can I create conditions for a duplicate?

Hello,

Thank you for reaching out to us. 

My apologies for the confusion, but I'm just not sure of what do you mean by 'create conditions for a duplicate'? Kindly provide us with additional information for your form requirements? If you are referring to a condition to pass a value to a different field please see this guide: How-to-Pass-Field-Value-to-Another-Field

Thank you. Looking forward to your response.
