creating pricefinder using drop-down menus

I'm no techie, but I've been doing sites for a while and have always gotten help when I needed it from the user forum wizards. Been stumped for a week now and no help! (gulp)
Trying to replicate a site that uses a form with drop-down menus. Changing the menu options brings up the corresponding price and a "price matrix" (but all the pages have the same html name, which I don't get!)

Using their code, I was able to recreate the menus and they do change as they're supposed to, but can't figure out how to bring up the correct price/price matrix -- and I don't see anything in their code that tells the page what to do EXCEPT change the menu options!

The site I'm looking at is http://www.digitalprintingcompany.com

Please help -- i can't do this myself! Thanks.

This sounds like Javascript. It sounds like you want to look into OnChange events. In other words, when a value is changed in one menu, a corresponding set of sub options is displayed in a second menu, or a calculated value is displayed in a text box. I'm guessing here as I haven't looked at the example you provide, but Javascript OnChange events are probably worth investigating (or looking for in the page you're modifying).

Don't rely on Javascript to validate any of this data, especially where money is concerned, as Javascript is easy to fiddle with on the client side. You should always validate data properly on the server side.

I would prefer having the javascript code instead of providing an http link,yes it is performing what is required but then its javascript code is not available in the main html code.
Please if you don't mind you can send me that part of implementing that calculation.
