Clicking on Next button is moving to next page

We're having issues with anyone outside the United States being able to complete this test form that I setup.

They cannot click on the "next" button to move from screen to screen.  Says it's not working.  We've asked them to try different browsers all with the same result.

It seems that there is a conflict with the other scripts on your webpage. When I check the your JotForm using its direct link, it is working fine. Please try embedding the form using iframe method and see if that resolves the issue. Please go through the guide below that can help you in getting the iframe embed code for your JotForm.
