    I would like know if is possible block submissions with the same "index" field


    For example I don't want that there are 2 submissions with the same personal tax code ("Codice fiscale" in Italy)

    I don't want use cookie or IP because more submission can be write from the same computer but have to be not possible write double submission

    I hope that I explain

    I do not think that it's possible in any way.

    A JotForm does not have the ability to access previously submitted data, so there is no way for it to check if a specific "personal tax code" was already entered in a past submission, and deny or allow a new submission accordingly.

    I don't mean to check data prevously are submitted

    but after the user submit a form the program could verify if a specific field was previsouly submitted

    and give an error if the field is duplicate

    The only workaround I can think of for that scenario is to post the form submission into a database. So a external scripting language (PHP) can search for fields and compare if they were filled before.

    Here you have a guide which might provide you a better idea
