Product: Excel-97 SR2

What I'm trying to achieve is within a VB script is
changing the text title of a Chart. In reading through
the on-line help file, it gives the following example:

With Worksheets(1).Charts("chart1").Axes(xlCategory)
.HasTitle = True
.AxisTitle.Caption = "1994"
End With

But when I cut-n-paste the example into my spreadsheet,
changing only the value for Worksheets and Charts to whats
appropriate to my spreadsheet (for example; Worksheets
("Sheet1").Charts("Chart 3")...) I get the following error
message:

- Andrew
Run-time error: 438

Object doesn't support property or method


I've checked, double-checked, quadtriple checked for
typing / syntax errors, but other than the changes
mentioned, it's exactly as in the help file! Unless the
help file example is wrong, I cannot find why am I getting
this error.
