Form : different results (with Javascript)

hi - can anyone help me for this ?
i want to make a test on my site, a kind of small survey.

The form should go like this (very important : javascript ASP - no PHP, no CGI) :

Questions :

1. when do you smoke you 1st cigarette when you get up ?
* - 5 mn (3 pts)
* 6/10 mn (2 pts)
* 31/60 mn (1 pt)
* + 60 mn (0 pt)

2. do you smoke when you are sick ?
* yes (1 pt)
* no (0 pt)

etc.....

for each answer the user gives, there is an amount of points.
at the end of the survey, i want to cumulate the points and to display one of the 3 results, according to the number of points

Answers :

0-2 points : non-addicted to cigarette
3-6 pts : merely addicted
+6 pts : very addicted

thank you for your help.. and sorry for my bad english !
