Need a worksheet where data can be entered but, once it is entered can not be
changed. The purpose of this is for accountability. Example: If you enter
a customers name on a worksheet and an amount of money they owe you should
not be able to delete/dhange that data in the future but only add additional
data to the worksheet.
