Triple column stacking chart

[Electric Julie]

I created a double stacking chart in 2003 Excel but now need to add a layer
to make it three data points in the column AND I'm now using 2007. Can
anyone help???

The double stack is comprised of two series. Add another series in the next
column and include it in the chart. The fact that you're using 2007 is
immaterial.
