After doing a few grouped column charts, I'm having difficulty getting my latest one to group. I'm thinking it may be in how I'm building my datatable, but can't seem to quite get it. Any help will be greatly appreciated.

Below is my html & code, then what the chart looks like and then what the chart "should" look like. Please help. Thanks so much!
