Hi, vQuiz isn't show the correct answer of the question.

Hi there!

Previously, I had set the correct answer of the question but on the front-end when I do a quiz, vQuiz isn't show the result of the question.
This is the first time for request your support. I didn't see the ticket support for customer or something like that. I only see this forum, I don't know where I can give you my back-office URL.
You can try to test your vQuiz from my front-end that is the page I found a problem by
this URL: nsm.megazy.com/other-services/vquiz/quiz.../science-2/play.html
The answer of the question is 2.
I already attached the problem that I found. Please help me check it.

Thank you.
