Is the nSeries the Total number of series?  If you had 1 series and wanted to add 1 more nSeries would now be 2. 

The following bit of code works for me in Access2k. Sometimes before I go "over the edge", I delete the control and reinsert it. Seems to help.

Steve

Private Sub Form_Load()

'set chart with 1 series

ChartFX1.OpenDataEx COD_VALUES, 1, 5

ChartFX1.Series(0).Yvalue(0) = 30

ChartFX1.Series(0).Yvalue(1) = 76

ChartFX1.Series(0).Yvalue(2) = 43.5

ChartFX1.Series(0).Yvalue(3) = 90.75

ChartFX1.Series(0).Yvalue(4) = 12.5

ChartFX1.CloseData COD_VALUES

End Sub

Private Sub cmdAdd_Click()

'add another series to existing chart

ChartFX1.OpenDataEx COD_VALUES, 2, COD_UNCHANGE

ChartFX1.Series(1).Yvalue(0) = 40

ChartFX1.Series(1).Yvalue(1) = 86

ChartFX1.Series(1).Yvalue(2) = 53.5

ChartFX1.Series(1).Yvalue(3) = 100.75

ChartFX1.Series(1).Yvalue(4) = 22.5

ChartFX1.CloseData COD_VALUES

End Sub
