Form Won't Move Ahead

I just purchased a plan today, and the first form I created won't let the user go past the first field. The button will be clicked but nothing happens. We've tried it on my computer and on two different smart phones, still nothing. Link below to try.

We are truly sorry for the inconvenience this has caused. The problem is now fixed. Your form should work fine now as usual.

Yes, it works. Thank you!
