I add a few input and dropdowns in my website. In the preview function, the button work perfectly fines. However, in the real posted website, the submit button seems not working at all. The fact that I have already input all the "must" boxes and then I click the submit button and it still appears a fail message. The problem is there is no red boxes appear (So I have already fill in all the must boxes) and then I try to fill in all the boxes including the optionals and the button still not working.
