First time working with zoho Forms.

First time working with zoho Forms.

Hello, I have a quick question I cannot find on your forms page. I am trying to create a rule to hide/show fields based on the user selecting a radio button. Now I would like to show only certain fields depending on what radio button is selected. For example, A customer can choose 1.) Rent 2.) Mortgage 3.) Own   
I have played around with the rules and looked to your tutorials but it seems that your form rules page has been updated and does not look the same when I am in the rules page. What I have is 1.)Basic Details 2.)Execute on 3.)Criteria 4.) Associate Task.

All I want to do is a simple task but it has me stumped at this time.

Thanks for any help you may have.
