Thanks for your persistence Ronald, but still no joy here. I set the "Round Cash Sales" to 0.01 and still the same. When I go back to the tax and precision setup, it has changed back to 0 with no .01. If I put in any whole number, it accepts and saves, but the extend column remains with no decimals. I have done a complete uninstall and reinstall with no luck, however when I try to set up on another computer, I have no prolems. Any more ideas? Many thanks, Darren
