Change Pivot Field function from xlCount to xlSum

Back again...

I have a workbook with several pivots, all using the same source data. When i update the pivots to include new data, they pivot field defaults to using the xlcount function... and i usually have to go in and check each pivot to make sure they are all changed to xlsum. I have been using the following colde to update the source for each pivot in the workbook...and have toyed with adding the lines to change the function to xlsum...
[vba]For Each ws In ActiveWorkbook.Worksheets

For Each pt In ActiveWorkbook.Worksheets(ws.Name).PivotTables
pt.ChangePivotCache ActiveWorkbook.PivotCaches.Create _
(SourceType:=xlDatabase, SourceData:=src)

For Each pf In pt.PivotFields
If Not pf Is Nothing Then
With pf
.Function = xlSum
End With
End If
Next pf

Next pt

Next ws[/vba]

I get a run timer error '1004':
unable to set the Function property of the PivotField class


The Excel Help offered no guidance...

Any ideas?

I think i have stumbled upon my solution... not sure what consequences there may be, but it seems to be working.

I changed the line
[VBA]For Each pf in pt.PivotFields[/VBA]
to
[VBA]For Each pf in pt.DataFields[/VBA]

Will still appreciate any alternatives or better practices...
