sales figures (Amount) categorized by Month, SalesRep, and Type. The worksheet contains
named ranges that correspond to the labels in row 1.
Figure 7-2: This worksheet demonstrates various counting techniques that use multiple criteria.
The workbook multiple criteria counting.xlsx is available on the companion
CD-ROM.
Several of the examples in this section use the COUNTIFS function, which was introduced
