"Incomplete Values" error

Hi - when trying to make a booking and then clicking the submit button I get a message saying "incomplete values" with a "go back" button that doesn't function.

Thank you for reaching support,

I made a test submission on the form and I was not able to replicate the issue as I was able to submit the form successfully:

Can you share with us a screenshot of what your entries are so we can try to replicate it?

Here is how: https://www.jotform.com/help/438-how-to-post-screenshots-to-our-support-forum.

Awaiting your response.
