Well, since no one seemed to have any ideas I did some more work on
this and found a work-around.

These lines are inserted in the appropriate sections of teh code.

myrng="R" & ro & "C" & col

And then;
SourceData:="Received!R1C1:" & myrng

That gives me the flexibility I need and keeps the dreaded error 13 at
bay.

Hi folks,
When I run the following macro I get a type mismatch when it tries to
create the pivot table. The commented out section works but I need to
have the flexibility of using the variables for the bottom-right edge
of the data as that changes daily. The section that gives me the type
mismatch here works exactly as written in another macro. Very confused,
I am.
Thanks,
Bill
