    That can be accomplished by using our Unique Question function in the Form Limits settings. That will prevent the person from submit the form if the entry of a specific field is the same of a previous submission. Please follow these steps to enable it.

    1. Go to Setup & Embed tab.

    2. Select Preferences.

    3. Click on Form Limits tab.

    4. In the Unique Question option choose the field you wish to accept unique entry.
