Doughnut chart 2 rings help

I have a 2 ring doughnut chart that graphically appears perfect, but I'm wrestling with Excel 2010 on the series labels.

Series 1, the inner ring, shows 3 different product line components displayed as a percentage and totaling 100. I have the component name in a column next to its percentage.

The outer ring shows 2 business groups, showing what percentage of the inner ring as a whole they use, again totaling 100.

It looks perfect, although I'm having a problem with the fills. (Struggling to show each data group in a ring with a different color, despite making sure that option is chosen under formatting options.

The head banging problem is that I can't force Excel to use the data label range for each series for that series. The individual percentages (values) are correct.

Where I see the problem is in the "select data source box" where I show each series in the left pane and the horizontal axis labels in the right pane. Since I can't figure out how to plot on a secondary axis, its forcing me to choose one set of labels or the other for the whole chart.

I have forced a work around by using text boxes, but I'd rather be able to do this automatically.
Thanks in adance.
