run-time error '1004': unable to set the ColorIndex property of the Interior class
 

I've selected a chart and when I try to run the following code inside
of a sub routine, I get the run-time error '1004': unable to set the
ColorIndex property of the Interior class

ActiveChart.SeriesCollection(1).Interior.ColorInde x = 3

Any help is appreciated.

I figured out my problem. I was trying to use Interior when I should
have been using Border.
