Depending on the type of your data that may well be how Excel behaves
If e.g. you data is as follows
<CODE>
Sold
Items Jan Feb etc
A 12 14 5
B 10 22 36
C 100 99 75
</CODE>
and you create a pivot table it will only Grand total the columns.
(items in row, month in col)
To fix that add a totals column (=sum jan-dec) to your data and then include the total col it in your pivot range.
If your data is e.g.
<CODE>
Name Dept Country
Joe HR MY
Jane RE NL
Bill FN UK
</CODE>
and you create a pivot to sum names by Dept (row) country (col) the pivot will give you a Row Total (and a col total).
Apologies for crappy code, I cant install HTML add-in in office.
