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 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!!
