As for discounts, it was not subtracting them from the total, nor was tax being calculated as a negative. Once again, the tax on this discount should be read from the database.

Now the issue I have is that the email does not work when updating the status or comments. I tried looking at the orders.php file to see what was different. The call to zen_mail was different. I fixed this up, but still have the same problem....

Email Error: Could not instantiate mail function. Please check Admin->Configuration->Email Options->Email Transport

Anyone else have this problem? I can't see how the edit_orders.php version is any different than the orders.php version.
just curious, how did you fix the tax problem, can you be more specific to what change you made please.
