pivot table total rows

Hi-

Does anyone know how to total (sum) rows in a pivot table? Table options-grand totals for rows does not work.

Additionally, when I put all the expressions in (Expr1, Expr2 etc.), the first was sum of Expr1, the second count of Expr2 (which I changed to sum of Expr2). Does anyone know why I had to do this?

I have attached a spreadsheet (Excel 2000).

Thanks,

Tim
