[Plugin: mTouch Quiz] Not working well

Hi,
I added 10 questions and all seemed to be fine. But when trying to view on front-end I have several problems:
1. questions are not in the right width and every questions shows with text cut and half text of next question.
2. when choosing an answer, nothing happens…

This is the page:

Thanks 🙂
