Thanks!
I checked all of it and the problem was that the Location Zones were not defined. Once I defined them, the checkout calculated it at checkout but not the way it was supposed to.
I mean in my country all receipts work a bit different. If I put x price for a product (as is shown in the product page), that's is supposed the final price including taxes --I mean the receipt is supposed to show three things:
1- The price without the tax
2- The tax (20%)
3- The total that is the sum of 1&2
For example if the description page says that the price is $120, then at checkout and later in the receipt it should be described as:
Subtotal=100
Tax=20
Total=120
But AbanteCart applies the tax after what should be considered as the total price and obviously that is not what we need in our country.
Is there a way to work around this?
Thanks!
