Tom,

Thanks. That reference was already set and there was also a
ATPBVAEN.XLS listed that I referenced. That didn't help...and I
thought it odd to have an XLS extension since the toolpak was an add-
in.

I understand your comment about the range reference. SourceData is
the activesheet since the cells reference works. I'm an engineer and
think better in a numbered gird (R1C1 reference). How can on make
reference using the (r,c) notation on anything but the activesheet?
In other words, how can I use (r,c) without also using cells(r,c)?

Thanks,
John

in the vbe, Tools=References, select the analysis toolpak.

That would allow you to call Histogram like it was a built in function, but
since you are using application.Run, you shouldn't need a reference.

this kind of reference:
SourceData.Range(Cells(StartRow, 2),Cells(EndRow - 1, 2))

is inconsistent.

If in a general module:
If SourceData is the activesheet, it works, but then there is no reason to
have the qualifier SourceData. If SourceData isn't the activesheet, then
Range refers to the sourcedata sheet and Cells refers the activesheet and
raises an error.

With SourceData
Set HistData = .Range(.Cells(StartRow, 2),.Cells(EndRow - 1, 2))
End with

Would be consistent and avoid errors. There is a similar type problem if
the code is in a worksheet module in that the unqualified references refer to
the sheet that contain the code.
