WebPlus X6: Combining Form and eCommerce

Hi everyone

So I am looking to add online payment system for an upcoming scout family camp.

Here is our old one, which isn't really too use friendly. http://www.23rdbromleyscouts.org/familycampbooking.html

My question, is there a way to combine the Serif Web Resources form and the eCommerce function? For example, when you click submit on the form, it takes you to a payment section. There is information we would like to capture separate from the payment information.

Anyone have any ideas what the best way round this will be?

Thanks
