Getting multiple registrations because clicking back in window.

I have a form that´s been getting duplicated responses, it seems the persons are hitting the back botton in the browser, the form comes back filled and if they hit submit I get another registration. Is there a way that if they hit back in the browser, they get and empty form?

oh, another important thing, this form is embeded in my site

Thanks

You can setup Unique Submissions in your form to prevent multiple submissions from being sent. To do so, simply follow this guide: How to Set Unique Submissions on a Form.

If the issue persists, please share with us the url of your webpage so we may further investigate it.
