    How to set Unique Submissions on a Form

    Asked by sayrekulp on December 09, 2013 at 09:42 AM

    Is there something in the software that prevents multiple forms from being submitted from one computer terminal? Maybe something checking the IP address? Our form been rather successful, except for when we set up a laptop at an event to take signups, only the first one went through even though the additional forms were completely different. Is there a way to stop this from happenning in the future?

    We have a feature called Unique Submission in order to achieve that in your form. To set Unique Submissions on a Form, please follow this simple steps.

    1. Open "Setup & Embed" tab on toolbar,

    2. Click on "Preferences"

    3. Go to "Form Limits"

    4. Select the Unique Submission option you prefer.

    5. Close and Save your Form.

    If you select Strict Check, people in the same network (in the same school, college,university, institution) will not be able to make submissions, as the IP address for the network would be the same.

    If you need further assistance, please feel free to contact us again at anytime.
