Hello,
I'm having the following problem: I have this contribution installed: http://addons.oscommerce.com/info/2729, which is just another way of displaying an invoice.
At the end of the invoice, of course, the subtotal is calculated - BUT: in Germany we have to different taxes (7% and 19%) and my tax counselor wants me to have two different subtotals on the invoice - one for 7% and one for 19%.
So far I've been desperately searching the net but haven't found a solution so far (I have very little PHP/SQL knowledge).
Could may someone help me with this problem?
Thanks in advance!!
