Basic Hints
Questionnaire viewer is implemented in a way that you can add javascript to manipulate the way your questions are displayed. Thanks to jquery, javascript has even more powerful effect! (read more about jquery here: http://jquery.com/)
Javascript is a property on both question and questionnaire levels, which means that you can add javascript for each question or for the whole questionnaire.

- quest: the current question's object
- questioncheck: the function that will be called before going Next
