Reference an existing website with a custom HTML order page containing four line items consisting of one text field and three drop down boxes, and a readonly field positioned alongside each one. All fields reside inside one set of form tags. The text field holds up to ten alpha characters denoting the first name or initials entered by the customer. The cost for the first line item is determined by the number of alpha characters inside the text field multiplied by $2 each. The cost for each of the remaining line items containing the drop down boxes, if and when an item is selected, is $2 for each line item and remains $0.00 if nothing is selected. The readonly (price) fields to the right serve as calculated fields to show the price of each line item.
My question is: before making the jump from ShopSite Starter to ShopSite Manager, is it possible to integrate the shopping cart using the ordering options featured in ShopSite Manager together with only one 'Add to Cart' button to allow for adding all four line items described above to the shopping cart with just one click once the customer has completed their selections?
