I am having problems with the tax. the order is discounting properly, but the total is not adding up...

[FONT=Courier New] Sub-Total: $40.00
Flat Rate (USPS Flat Rate Shipping): $5.00
Quantity Discount: -$5.00
98110 Bainbridge Island 8.80%: $3.52
Total: $48.52
[/FONT]

I am using the local sales tax mod (V2.0) by Heather Gardner (LadyHLG). It is not subtracting the Quantity Discount. By the way, I am using the Quantity Discount basis of "Total Items in Cart". I saw a bug and resolution earlier, but have no idea where to make the code change.

thx....
