How to connect survey to headquarters?


I am working on a research project and we have designed our whole survey on We conducted our pilot interviews, however when we tried to extract the data we are unable to do so.

From the documentation I have read, I have realized that a headquarters need to be set up. I have tried doing that but I have failed. If someone can guide me step by step that would be helpful.

Thank you very much in advance for your support.

How did you conduct your pilot interviews?
