    Hello grafico,

    You can have your form only allow one submission by adjusting the unique submission settings of your form.

    To do this:

    1. Edit your form
    2. Click Preferences (a pop up will appear)
    3. In the pop-up window, go to Advanced Settings tab
    4. Under Unique Submissions, click the value on the right, then you can select a drop down of options:

        a. No Check - A form user can continuously make submissions
        b. Loose Check - This type of checking is just based on cookies, once a form user deletes his browser's cookies,  or if the user is using a different browser, he can still make another submission.
        c. Strict Check - This type checks the IP address.  Only one IP per submission.

    If you have other questions or concerns, please let us know.
