Customer Discount - Checkout showing wrong numbers

[disciple1]

Hello,

 

I have installed the customer discount contribution. In my testing I have found that the numbers aren't showing up correctly in the checkout confirmation page.

 

Here is an example of the problem I am running into:

 

Sub-Total: $19.95

Customer Discount: $9.95 (50% discount should show $9.98 )

AZ TAX 8.1%: $1.62 (tax should show $ .80)

United Parcel Service (1 x 3lbs) (Ground): $7.26

Total: $18.08 (total should show $18.04)

 

Can anybody help? I have tried contacting the author through their website but have not yet had any luck with getting the problem solved.

 

I am using 2.2 ms1 but I think this contribution was written for an earlier snapshot.

 

Any direction would be greatly appreciated.

OK, after some more searching I have found part of the solution. The discount that was not being figured correctly was fixed using this thread

http://www.oscommerce.com/forums/viewtopic.php?t=32375

 

Everything adds up correctly now but the tax is still SHOWING the incorrect amount. It must be figuring it correctly since the total is correct. Can someone tell me where to look and how to fix the tax amount that is SHOWN.

 

The tax is showing tax on the original amount instead of the discounted amount.

 

Thanks
