Forminator error messages and won't submit form

I created a form using Forminator and included it in a post for my customers to complete their annual registration and when I tested it, my submissions were logged and viewable - however, now that I've posted it and my users are trying to submit them to me there are problems that I can't find the cause. My users are getting error messages and none of the forms have been saved in the dashboard.
The form is located at http://www.kamkartway.com/2019-driver-registration if you want to look at it and maybe offer a solution on how to remedy the problem.
Thank you in advance for your time and help with this issue!!
