Receiving duplicate submissions

I am receiving duplicate submissions, sometimes one or a few days after I receive an initial submission.  It happens with my OPI Breakfast Order Form only, not the pizza menu, and not to all.

How do I correct this and am I using up my submissions?

Thanks so much,

Bruce

Hello Bruce - I was able to see that some of the submissions are, indeed, duplicated but with different timestamps.

If they didn't submit it intentionally, then it's most likely due to this option in the browser settings "Continue where you left off", where the last visited URL is kept (e.g. form's thank you page) and some browser reloads it automatically when you open the browser again. Some mobile browsers also use this option by default.

It's possible that your user's browser kept the last visited URL which is your form's thank you page after they made their first submission. And when they open their browser again at a later time, it automatically loads the thank you page and creates a new submission with the same previous data initially submitted by the user. Some browsers do not reload the URL automatically but it would definitely be an issue when the user reloads the thank you page manually.

To prevent this, please use an external thank you page rather than the default thank you page for now. So when the user opens the browser, it loads the external link instead of the default thank you page and this will not trigger submission. 

Here's a guide on how to redirect to an external link after submission How to Redirect to a Page After Form Submission. If you don't have a custom thank you page, you can use this link https://www.jotform.com/thankyou.html
