Hi Shivendra,

This is all pretty basic OutSystems, but at the same time also non-trivial work. Your question to me reads like "I don't know how to program, please write an app for me", which is not what this forum is intended for.

First, make sure you have followed all OutSystems beginner tutorials, so you have a firm grasp on the basics of OutSystems. Next, develop the data model for your questionnaires, then create the screens and associated logic. If you have a very specific question about a specific part of your app, please come back to the forum to ask it.

I'm going to close this topic now.
