Is the worksheet protected?
Have you grouped multiple worksheets?

And make a note of this--just in case you notice something different with your
subtotals:

Multilevel subtotals are in the wrong position in Excel 2002 and Excel 2003

Am I going crazy? I just got XP today with Excel 2003. I know everything
looks a little disorienting. But, I've got a basic spreadsheet, I'm trying to
apply subtotals and the option is greyed out as is outlining.

Is there a problem I don't know about. Any ideas why?
