In your example of building a Quiz, the bottom of the page gives you a link to the previous question. Is there anyway to make it a BACK button and put it right along side of the SUBMIT button? While I am on the topic, Is there any way to make the SUBMIT button say NEXT for all pages except the last, where it woudl say SUBMIT?
