Looking for something specific (conditional form with math calcs)

Hi
We have a product category in our online shop for windows and doors anti-mosquito screens (aluminium constructions)
We need to create a conditional form with math calcs for the customers that they need these products and be informed about the prices. Here is a little example

  1. Choose between door and window screen
  2. Choose the right width ( for example a window with 35cm)
  3. Choose the right height ( for example 80cm)
  4. Choose the color (white, wood, ral colors)
  5. Click submit
    The result will be one or more products from 3-4 diffent categories
    with prices based on 2-3-4.
    I need to inform me about a scipt that works that i can put it on a wordpress webpage
