Issue running Macro with Pivot Table

I made a macro that works fine on my computer, but when my coworker tries to use it, she gets an error message when the macro tries to create a pivot table. It says Invalid Argument

Receiving error on this line:
ActiveWorkbook.PivotCaches.Create(SourceType:=xlDatabase, SourceData:= _
"Sheet1!R1C1:R8673C35", Version:=6).CreatePivotTable TableDestination:= _
"", TableName:="PivotTable1", DefaultVersion:=6


Does anyone know how to edit the line so that it works on my coworker's computer?
