Submit Button Not Changing Questions

I am building a cute webpage for my teacher (who's very fun) as a Christmas present, but whenever I enter text into the input box and submit any question past the first, the code marks it as incorrect. I thought I had fixed this problem when I changed the question submit, every time the question changes, but apparently not. Can someone tell me what I'm doing wrong?
