I have a pivot table in a worksheet that is based on the data from another
worksheet in the same workbook. The data worsheet has 17 columns (from A to
Q) with 62410 lines worth of data.

When I view the pivot table's list of available fields, I have 18 fields,
not 17. So I naturally thought that someone added a calculated field. But
when I looked, there is no extra calculated field. This extra field only has
about 5 values and I don't know where these 5 values are coming from.

Aside from the data source or calculated fields, I'm wondering if there is
another way of adding a new field in a pivot table. Can anyone help me? I'm
stumped. This workbook was given to me. I did Ctrl-F to find the 5 values in
the data worksheet and they are NOT there in any column.

Help !
