Getting a message that only one submission is allowed

I set up a form at: https://www.jotform.com/build/90171732000946 While testing the form I keep getting a message that only one entry is allowed. What is causing that? Please advise.

You've set a unique submission limit in the form - based on cookies. You have to disable the limit if you want to allow multiple submission from the same user.
