I cloned your form and made some tests there. I filled the form and submitted it, and it appears that the form shows the result on the Thank You page without any issues.

Can you please try re-entering the correct answers on the Quiz Form app? http://quizform.jotform.io/
Make sure that the "Show Results After Submission" is checked on the options of the quiz form app.
