    Hi lssf,

    You can prevent that by enabling the using the uniques sumission feature of JotForm. There are 2 options to choose from. First, by using the Loose Check, this uses a cookie to prevent them by submitting twice. Second, you may use Strict Check, this option uses the end user's IP Address to prevent them from submitting twice. To enable these options, please follow the instruction below:

    Please let us know if you need further assistance.
