Rewards Points - US Park

I am trying to sign up for the rewards program with US park and I got an email link asking me to create an account.  This looks like a survey website.  How can I go about trying to get rewards points for my past receipts?

I'm sorry, are you referring to Get more section: https://www.jotform.com/myaccount/getMore to gain more submissions limit?

Or you were referring to something else?

Please advise so we can assist you further?
