Forms Question: Adding selections on the fly

[PharmerGuy]

Hey all:

Long time viewer - first time poster.

I am building a forms based HTML doc for our company for someone to order an item based on user defined specs (think Dell.com when building a computer). When the person selects, say, a processor speed (all of which are different prices listed) - I want a spot at the bottom of the page to automatically tally up the price difference. How do I do this?

All help is much appreciated!!!
