it looks like this:
intermediate total: 97,99EUR
overall forwarding expenses (): 6,70EUR
Cash on Delivery : 3,68EUR
Sum: 108,37EUR
MwSt. 16.0%: 14,44EUR
16: 0,51EUR <- These are the taxes from the Cash on dlivery!!!
Which php site is for calculating this tax? I just found a site, where i can make string behind the 16 (is the descriptionof the tax !)
