I tried every combination, including moving the Group Discount aboce the shipping. Here's what I am required to do:

I need to charge TAX on Shipping so I have my Tax Class as Taxable Goods within the table shipping module. I have set the Tax Class to None within the table module and everything calculates as it should.

HOWEVER, I am required to charge tax on shipping. So, how do I do the following (still not convinced it's not a bug, or a very confusing way to do things):

1. Charge Tax on Products
2. Charge Tax on Shipping
3. Allow for Group Discounts and Discount Coupons

Doing all three causes calculatiosn (in every order I try) to be incorrect. Can you try this in a test store? I have tried this in a test store with no code modifications to the tax, order total, or shipping code. Thanks.
