Hide answers/rows of a form

,

Hi everyone,

First of all, excuse my English, I am from Spain.

Well, I have a created a public app just to make surveys, the app is used by 50-60 people. They just need to fill a form with the info I want to collect. The thing is that everytime the fill the form they can see the info of all the rows added to that table. How can I hide the info of the rows so they can just see the form they need to fill? I am not interested in user sign-in because it will make the app very expensive.

Thank you all for your help,

Manu.

The question is how do you want to filter those questions… depending on previous answer? With something else?
