Trying to find the % change (up or down) for the following data series. That
data includes zeros and effects my formula
Example:

Column [b] is 2006
Column [C] is 2007
Column [D] would be the formula column showing % Change
if Column [C] is < Column [b] then % would be negative
if [C] is = [D] then no change or zero.

CELL = [A1],[B1],[c1]

DATA:

SalespesonA,0,5
SaespersonB,4,6
SalespersonC,6,0
SalespersonD,8,3
