Thanks, that helps.

Now, how can I reference this in a chart data range. If I edit the
formula and press F9, I see the array. However, I'm trying to use this
as Values in a Source Data range in a chart. In the chart, I'll edit
the Values and select the cell with the array but only the first value
appears in the chart. If I type in the array ={1;2;3;4} in the Values
field, it displays fine.
