Customer gets stuck on quote?

Hello, I don’t have a link to my cost calculator because I am not pushing it live until this problem is fixed. My problem is as follows: when a customer pushes the button to see the quote, there is no way to get back to the web site from that quote. The quote has no way to “x” out of it, nor a backwards error to go back to my pricing page. Is there a way to disable the quote button altogether?
