Creating quiz in Flash using XML - Help me

[NoPeasHear]

I don't know what I am doing wrong...

I used this tutorial...
http://www.permadi.com/tutorial/flashMXQuiz/index.html

It works with their quiz.xml file, but when I add an option for multiple correct answers, the results page always gives me a response of 0.

What would I change from the tutorial to have multiple correct responses reflect in the results?
