Web based product configurator

Hi, We would like to make an web based product configuration, which should run inside an existing website. In the following text i refer to attached PDF files with number where the web pages are visualised. A short description of how we would like it to function from the point of view of a customer. The customer arrives at the product list page (1) where they can choose a model. After choosing the product the customer is guided through the product configuration by choosing options(2) from a list. When all the options are chosen the customer is taken to the product overview page where they can complete the transaction. The method we would like to propose for saving what options are chosen is to letter code every option and product. Here is an example; We have product 1 We have option Gold = G We choose product 1 and option gold, so 1+G = 1G Generated complete part number for the transaction is 1G I would like these letters of the various options added onto the chosen model number and then save the generated string of letters to form the generated complete part number. Then represent this in the last page which is the product overview (3) where the final price is calculated and order completion options are given. If you have any questions just ask. The design is not that important, what is is the possibility to do data entry of the products and the options so we can change or add items. Kind regards, Stijn
