I am trying to add columns to my Excel 2010 Pivot Table to calculate % change of sales from year to year. The field name is "Year", while the item columns in the field are 2007, 2008, 2009, 2010, and 2011. How do I add a column between the years that will calculate the % change os sales up or down from the previous year?

Any help GREATLY appreciated!!!
