I believe the field defaults to SUM if all referenced cells in that field
contain numbers. It uses COUNT if any of the cells contain blanks or text.

Does that help?

Why, in pivot tables, do I sometimes get "sum" and other times
"count" when putting fields in the data section? I import data
from CSV files, and in one file I am trying to get the sum of
invoices (and I get count) while in another I am trying to get the
sum of purchase orders (and I get sum).

Thanks for any insights.
