I know. There is no tax calculation after I set the billing state. The tax usually appears after entering all billing and shipping information in the checkout.php page where you enter the credit card information and submit the order. But no Tax is calculated - not even in the checkout_success.php page.
The system somehow seem to recognize the information in the eCart object because once I remove the tax rule from the eCart object = tax is calculated regardless of state. It is just once I enter the state (NC) as described above that no tax is calculated at all.
Here again is the result of the dump session code that you asked me to put into the confirm.php page. Can you identify the session value in this result?
