I've noticed a strange thing.
Example:
Item Description Qty Sub-Total Tax % Tax Amt
Product 1 SEK192.00 25.00 SEK48.00
Sub-Total SEK192.00 SEK49.00
Shipping (Shipping Rates) SEK50.00
Total Order Charges SEK242.00 (excl.tax) SEK291.00 (incl.tax)
Why does the calculation add an extra 1 SEK tax on the sub-total calculation?
192 + 25% = 240
240 + 50 = 290
AND NOT 291!
