Customer Discount values not displaying correctly

[disciple1]

Hi,

 

I have downloaded and installed the Customer Discount contribution with no problems. The problem I am having lies in the values being displayed when checking out.

 

EXAMPLE:

 

Sub-Total: $39.95

Customer Discount: $20.00 (50% discount should show $19.97)

AZ TAX 8.1%: $3.24 (tax on discounted amount should show $1.61)

Free Shipping (w/ $25.00USD minimum order): $0.00

Total: $21.59 (the total is correct)

 

So the total is using the correct values but the checkout is not displaying them correctly.

 

My sort order is as follows:

Sub-Total = 1

Customer Discount = 2

Tax = 3

Shipping = 5

Total = 99

 

Include shipping in calculation = false

Include tax in calculation = false

Calculate tax = true

 

I have played around with sort order and the radio buttons for inclusion or exclusion of options but have not figured out how to make the values display correctly.

 

Any help on this would be greatly appreciated!!

 

Thanks

 

Rick

 

P.S. I am using the download version of oscommerce2.2 milestone 1

Sorry forgot to mention that if the sub-total does not have extra cents involved, in other words like $21.00 then the 50% calculation shows up correctly but the tax still does not.
