Pivot Table Column Names

When I record the creation of a pivot table, and choose for my data source columns A:D, the code recorded for the column selection is similar to this, showing C for columns 1-4:

ActiveSheet.PivotTableWizard SourceType:=xlDatabase, SourceData:= _
        "'Summary View'!C1:C4"

I then put that same code back into my macro, looking like this:

ActiveWorkbook.PivotCaches.Add(SourceType:=xlDatabase, SourceData:= _
        "'Summary View'!C1:C4").CreatePivotTable TableDestination:= _
        "'[Regional CPS (Put in Date) Filled Compared to Target-Full.xls]Summary View'!R1C16" _
        , TableName:="PivotTable1", DefaultVersion:=xlPivotTableVersion10

However, when I run my macro, instead of the source being Columns 1-4, the source is column c, rows 1-4. How do I tell my macro I want columns 1-4?

Let me rephrase, so maybe someone can steer me in the right direction:

When I RECORD the creation of a pivot table, and I select columns A-D as my source, the code recorded for that selection is:

"'Summary View'!C1:C4"

When I PLAY BACK the macro, "'Summary View'!C1:C4" is interpreted as Column C, rows 1-4.

That's a problem for me, and I don't know how to overcome it.

Okay, so I'd have to include a "lastrow" variable. How do I write my range in creating the pivot? Something like this?

"'Summary View'!A1:D" & LastRow
