Another problem I have is this. The values of the Tax and the Shipping are got from a session variable TaxRate and ShipRate, that is why when you reach the checkout page you have to select a country in order to get the proper values from the database table (see a screenshot of the table)
If there is a value in both the tax field and the shipping field, then the cart shows both lines at the confirm page, but if the tax value is 0 and the shipping is 8 euros, then any of these lines appear on the cart, although the sum of the 8 euros for shipping is well done at the grendtotal, but the lines of Tax and Shipping do not appear.
How can this be solved?
