I am looking to recreate a form function like this website:

http://www.plus.approvedtelephonesystems.co.uk/UK/questionnaire7/uk-companies.aspx?gclid=CLSH-eTeg60CFQUhtAodyhSNTg

What happens when you click the answer to the question the form scrolls to the next function. I would love to know how this is done. I am not a javascript developer but having looked into this the form uses scriptaculous.js and prototype.js.

Is there an online form builder or a program out there that can re-create this or is it just a simple bit of javascript added onto a form?

Thank you for any help!!!
