How do I allow multiple submissions in the form?

Hi,

I received your answer but I am not clear on the drop down menu I don't have the option to select (Loose Check) or (Strict Check). The three options are No Check, Check Cookies only, and Check Cookies and IP. I just want to restrict multiple submissions to the same event. The answer you gave me is not clear. Please advise!

Thanks for your help
