[URGENT] Tax not charged correctly!

[D.J.]

OK, I need help ASAP as I have already charged people wrong amount!

I have a 20% tax on all products, the net and gross value are correct. But the invoice looks like this:



The correct should be:

Product 24,50
- Coupun 2,45
+ Shipping 3,0
= SUM 25,05
= Tax 4,175

Does anybody have an idea how it calculates tax and what this sum is?? I do not need any other tax charge other than the one in gross/net in product prices!

Please help!
