Quiz does not start

I’ve created a quiz and embedded it in a blog post, but the “Start quiz” button is not working. After looking at some support forums, I’ve been attempting to get the [raw] shortcode to work by editing my functions.php, but it doesn’t seem to work. Any ideas?

Test post is here: https://corporate-citizenship.com/2013/09/26/5991/

Thanks,

Charlie
