Why can my clients not submit their form after filling it out?

My clients are unable to submit their form after filling it out. And if they email it to me, it comes back blank.

Hi Samantha,

Thanks for reaching out to Jotform Support. 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 also tested it on a mobile view and I was able to submit it on mobile view as well:

I have cleared your form caches as a precaution, test it again after clearing your browser cache. Also test it on a different browser or a device. If the issue persists, we'll do a more in-depth investigation and work on finding a solution.

Once we hear back from you, we'll be able to move forward with a solution.
