discount calculation... with a server session variable.
I've set a Session variables on my Ecart. This variable is related to a field in my "customer" table that defines the discount that customer is entitled to (the field is set to varchar, but I think better to change it...).
By the way, how can I set up the calculation on the ECart wizard in order to have the Subtotal price deducted of that discount variable?
All the procedures explained I found are too clumsy and not clear, so a sort of step by step would be the best.
Just for the sake of the example, the Session variable name is "CustDiscount".
Thanks in advance for your help
