I want to have the ability for my users to select from several options and have it automatically update the prices, like when you Build-A-Computer with Dell. You choose your OS, then your harddrive size, your ram, etc and it will "recalculate" based on your choices.
I want to know how this is done - database? Java? JScript? What's the best/easiest way to do it? Not how Dell does - I already looked. :)
