REMARKS

* This function was added in Excel 2007 to replace the COUNTIF function.
* For an illustrated example refer to the page under Advanced Functions
* This function includes hidden cells.
* This function is not case sensitive when matching text strings.
* This function supports wildcards (? and *).
* Wildcard character: ? = a single character.
* Wildcard character: * = multiple characters.
* To include the actual wildcard characters use a tilde prefix (~?), (~*) and (~~).
* This function uses the actual cell values and not the displayed formatted values.
* The "criteria" can contain wildcard characters.
* Every additional range must have the same number of rows and columns as "criteria_range1".
* Any empty cells are considered equivalent to a 0 value.
* You can use the COUNT function to return the number of non blank cells with no conditions.
* You can use the COUNTA function to include logical values and text.
* You can use the COUNTVISIBLEIFS - User Defined Function to exclude hidden cells.
* This is similar to the AVERAGEIFS, MAXIFS, MINIFS and SUMIFS functions.

1 - What is the number of cells that have "Barry" in the range "B1:B5".
2 - What is the number of cells that have "Barry" in the range "B1:B5". Notice that prefixing the condition with an equal sign means the same thing.
3 - What is the number of cells that have "Simon" in the range "B1:B5".
4 - What is the number of cells that have "Barry" in the range "B1:B5" and have a value not equal to 20 in the range "C1:C5".
5 - What is the number of cells that have "Barry" in the range "B1:B5" and have a value equal to 20 in the range "C1:C5".
6 - What is the number of cells that have "Barry" in the range "B1:B5" and have a value greater than the value in cell "C3" in the range "C1:C5".
