Thank you very much!

This is because you have enabled the "Unique Submission" option in your "Form Limits".

You have set it to "Loose Check", this means if the users are using the same browser, they won't be able to make multiple submissions. Unless they clear their browser's cache or cookies. You can disable that option is you are not limiting your form submissions. Please refer to this guide to learn more about that feature: http://www.jotform.com/help/64-How-to-Set-Unique-Submissions-on-a-Form 

Let us know if you need further assistance on this.
