Name, Gender, Age should be freezed

Hi SS Development Team,

Interviewer fill up the information of Name, Gender and Age in roster and proceed to the next question. But, somehow reason the interviewer/supervisor go back to the roster and edit/modified those details while doing the survey on tablet.

I want to freeze those details once the above information were entered before submit. So, that the interviewer/supervisor could not go back and edit/modified those details. How do I do this task in SS script?

Please suggest or give me a perfect solution.

Thanks,
Sitanshu
