I am planning to use QuForm to design a heating calculator or air conditioning system calculator for end customers. The aim is to show the customer a small selection of products with, for example, 5 different steps (next page) on each page. As soon as the customer has decided on a product (on the first page), a number should be hidden behind each product (costs for heating and air conditioning). At the end of the five pages, an evaluation should appear that calculates (adds up) all the options of the products.
