field names at the top of the columns.




The FieldName is the name or cell, of the values to pick the Max from, such as "Value Of Stock" or I3.
The CriteriaRange is made up of two types of information.


   The first set of information is the name, or names, of the Fields(s) to be used as the basis
   for selecting the records, such as the category Brand or Wattage.
