    Hello,

    Sorry I guess this question was related to your other threads question http://www.jotform.com/answers/383156?

    You can put restrictions like "Loose Check" and "Strict Check" so user won't be able to submit mulitple times.

    Loose Check - This checks the cookies of the form submitter.

    Strict Check - This checks the IP address of the form submitter.

    Here's a detailed guide of how this two features works http://www.jotform.com/help/223-How-to-set-Form-Limits-Based-on-a-Unique-Question
