I am attempting to write a formula using the countif function.  The
formula needs to evaluate a list of ages and determine the quantity
meeting the range and a certain race.  For example, column a has a
list of ages and column b has the letter b or w, denoting black or
white.  I need to be able to analyze the list and return the number of
individuals that are between 21 and 25 and are black.  I need to be
able to analyze the list for the same range of ages and white.  Any
suggestions.
