Pivot Table - Calculated Field

Hi,
I think this site will get you on track
Cheers

Yep... you don't need a calculated field. Do one of two things:

If you just want percentages, right-click Count of ID in your pivot table...
Field Settings --> Options --> Show data as: % of row.

If you want counts & percentages, drag another ID field into the data area of your pivot table and perform the steps above on one of the ID fields.
