Looking for some help on this form I am building.

invites.fasken.com/skiday_07/rsvp.html

The very last question for ski rentals has 2 radio buttons. YES and NO.

What I need it to do is when some one Submits the form with NO selected for rentals they are sent to a thanks.html page. But is they select YES I want them directed to rentals.html page.

Please help

Thanks!
