how do i calculate in Publisher?

[Germanator]

I have set up my publisher web site; I have added an "Order Form" which will
email after clicking submit. Now I want to link some fields:
I have created a list box with my products, now I am stuck. I want to link
the list box (with my products) with a price table. If you select a product,
the price shows automatically, then the customer chooses from another list
box the quantity he/she wants to order; box number 4 will automatically
calculate the total amount being <product price x quantity> = total price.
Shouldn't be too problematic but I am new to it. How do I do the above?
Thanks

What you speak of involves web programming versus web design.
Web design is the design of a "front-end" interface.
"back-end" logic is programming and requires a program on the server.
You'll need to review Asp, or Php, or Asp.Net, or Jsp, for example,
depending on the server's platform.
