You can see which function Excel has chosen when creating the layout; look
at the name: SumOfValue or CountOfValue. If you need to change it,
double-click on the entry ('CountOfValue') and choose a different function
under 'SummarizeBy'.

When I create a pivottable from some imported data Excel (2003 SP2) sometimes
chooses to summarize the data by using the function "count" instead of "sum",
which I then have change manually. What is it in the database that is
triggering Excel to choose either function?
