Is is possible to compare two columns in a crystal report. I have used the cross tab expert to produce a report similiar to the one pictured below, processing thousands of records to summarize by item # by year.


Item # 2006 2007
abc $20 $30

I would like to add a field that would print showing the perc increase/decrease between 2006 & 2007

Item # 2006 2007 Difference
abc $20 $30 50.00%

Any help would be appreciated.
