Try Lisp does not go beyond "Let's do a little math"

[skyflyer]

While using "Try Lisp", I can't go beyond "Let's do a little math". When I press Next button, I see that AJAX request fires (request is sent to /math) and the content retrieved is the same. Tested in Firefox, Chrome and Safari on OS X

Noted. I will focus on the Try Lisp section for the next couple weeks.

Looks like this is fixed in github but not on the website itself. There's only two additional pages after the math page so you're probably better off reading the online book.
