I would like to take two totals which are summed by groupings in the report and divid them to come up with the percentage of change.

IE, ((2003 revenue - 2002 revenue)/2002 revenue) * 100. When I do this under the group, it tends to total the percentages for each detail ( 4% + 5% = 9%) instead of recalculating for the summed amounts. What's the best way to get it to do what I want?

Also, what exactly does an * instead of numbers mean in the output?

Thanks,
Sunshine
