Hello and thank you for providing us with this.
I thought I had to start writing if else statements.

For test purposes I have read the file and followed to steps to create the following for 2 different counties:

Zone
Zone definition
Tax class
Tax rate

The one issue I have is that when I try to add a test product the "Tax Class" list show multiple choices to choose from... or
if I set one tax class all the tax rates are added up making the sales tax double the cost of the goods.

Where can I find complete info on how to set this up so when a customer logs in and wants to buy the goods from their county the correct tax rate is selected automatically?

What steps am I missing?

Thank you for your time.

Ohh and happy New Year!
