A picture is worth????
The attached spreadsheet [reports run 4.xlsx] shows the pivot results for 3 of many clients. It shows; (A) Client Name, (B) which reports that client ran, (C) how many of each report were run, and (D) the % of the entire report.
(Client #2 then ran 2.69% of all reports included in the pivot.)
I manually created Column E to show what % each report type is of the related Client's total reports.
(ie: 37% of Client #1's reports are Report C.) I want the Pivot table to generate Column E.
I think the answer is a Calculated Field that counts the instances of each report type for a client and devides that by the total count of reports for that client.
Hopefully that is less obfuscated.

And truly thank you for any help you can offer.
