Cant create this QUIZ (Javascript,html)

Question

This is my sample quiz. I am not able to display the result. Please help me I'm new to coding.

The quiz contains certain questions and I want the output to be such that if the user selects all the 'NO' options then it should alert conservative.. else .. aggressive else moderate.

Do i need to add validation to the below code?

 <table id="quizQuestion" style=" font-size: 14px; margin-top:20px; width:820px; text-align:left;" align="center">

You forgot to close your function. Add }; to the end of your javascript. Also make sure you're defining this function in the head.
