How do I integrate a dynamic form which calculates the price?

[vsj]

Hi,

I came across Authorize.net on this website 

http://www.rushessay.com/order/

How can I create the same form and functionality using Authorize.net?

Best wishes,

VSJ

authorize.net didn't create the form, it is whoever develope that website did.

You can do it yourselves, use one of the certified solution or hire a certified developer
