Hello, I'm quite new with webdesign and I can't figure something out. I'm trying to make something like this: http://www.ninerbenelux.com/Bike.aspx It's a form with some data behind it, when you change an option, the price and weight etc. will change as well. The form is no problem but how do I get the data in it and what kind of script do I need to let it calculate the price and weight? Is this doable or do I need to contact a professional webdesigner for this? Thank you in advance. Kind regards, Stefan
