Excel 2007 : Cluster-Stacked Column Chart Excel 2007

I'm trying to make a cluster stacked column chart. And I've found the site: http://peltiertech.com/WordPress/clu...column-charts/

However, I'm still having trouble doing what I want to do.

I've attached the workbook. Sheet 1 is the original data with a stacked column chart for grade. I would like to add gender and race, as well. I tried to reconfigure the data in Sheet 2 per the website above. Now I'm kind of stuck.

Any help would be great
