I need user to interactively enter sales data into six non-contiguous columns
each of which is a named range i.e. Date, Quantity, Rate, Net Amount,
SalesTax, Service
Tax. The rest of the columns are calculated from this data and are locked.
Data is filled as each transaction takes place.

Afer entry user should review and confirm before data is saved. Can someone
please help! I had posted this earlier but no success so far. Someone did
say it can be done. But not how!!
