Use the Worksheet object when you set the ranges...
Set rngValues = Worksheets("Data").Range(Cells(12, intAskColumn), _
Cells(intLastRow, intAskColumn))
Then use the range object as the location...
ActiveChart.SetSourceData Source:=rngValues, PlotBy:=xlRows

If you have more than one sheet to reference, it is best to always
qualify ranges with the correct sheet.

Please help -- why do the last two lines cause Error 438 "Object
doesn't support this property or method"?

Dim rngXValues As Range, rngValues As Range
Set rngXValues = Range(Cells(12, 8).Cells, Cells(intLastRow, 8).Cells)
rngXValues.Select
Set rngValues = Range(Cells(12, intAskColumn).Cells, Cells(intLastRow,
intAskColumn).Cells)
rngValues.Select
Charts.Add
ActiveChart.Name = "MyChart"
ActiveChart.ChartType = xlXYScatter
ActiveChart.SetSourceData Source:=Sheets("Data").rngValues,
PlotBy:=xlRows
ActiveChart.SeriesCollection(1).XValues = Worksheets("Data").rngXValues

The rng.Select statements work fine, so I know the ranges exist and are
correct. So what is the proper way to set the SourceData and XValues
properties? Thanks.
