Hello,
I've cleaned and imported a workbook with one worksheet and 11 columns (fields). All of the fields except one have the Aggregate symbol (sum symbol) in the Fields list except one. I've gone back and made sure that the formatting is the same (number) and the header to the column (field name) has the same formatting (standard) as the others and reimported the file (after deleting the first file). The same field still show no Aggregate symbol. Why is this and will it affect my reports (I presume yes.)
