I thought about that, the problem is it doesn't divide the Sum([2008]) for example into 3 approximately even groups. If you look at the output from the query you provided 59% of the sales dollars have a rank of 1, 28% have a rank of 2, and 12.8% have a rank of 3. I'm look more for a result of 33.3% for each group +/- a few %.
