Hi lustyprof, 

Thanks for reaching out to Jotform Support. Unfortunately, our Portuguese Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Portuguese, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, let me help you with your question. I'm not sure if I understand your question correctly. Do you mean they can't submit with your form? If so, I cloned your form and tested it to see if I could replicate the issue, but everything was working properly. Check out the screencast below to see my results:

I cleared the form cache from the backend, which resolves cache related issues. Can you try it again and see how it goes? If you run into the same issue again, let us know, and we'll do some more testing to see what's going on.

Give it a try and let us know if you have any other questions.
