cannot submit the form in the JotForm mobile form app

I’m also struggling to actually submit the form it keeps saying something is not right and highlighting red but I’ve got all the boxes filled in?

Greetings Lee Fairley.

Thank you for your message.

I have tested your form, and I was not able to replicate the problem.

Please make sure all required fields are filled before you submit your form. Questions with a red asterisk are required one:

After you try to submit the form, the error should appear underneath the problematic field:

If this appears even if the field is filled, please let us know on what field are you having the problem? Also, can you please send us a screenshot of the error? You can click here to see how to post images.

Thank you for your cooperation. 

Thank you... But did you guys figure out why I can’t download a pdf?
