The Total (net of tax) amount, the minus prefix, the & instead of ' and the Total (inc. tax) acount is wrong. Changing the default language to en_US calculates this result:
Code:
Total (net of tax) 1.00
Total tax 8% -1,996.00
Total (inc. tax) 2.00
Could my change in the main.lang to the german syntax be the reason for the calculation problem?
