13,263 PointsWhy isn't the html variable declared?
in the code at the bottom you have
"html = "You got " + correctAnswers + " question(s) right." print(html);"
I am wondering why it's not
"var html = "You got " + correctAnswers + " question(s) right."

If you want, you could report this as a bug to the Support staff.
