Hi

I have a pivot table, and in the values I have the count of sum fields.

Account| Count of Customers| Count of First Month Customers | Percentage new in the first month
New| 100 | 20 | Count of First Month Customers/countofcustomers

I want to add a calculated field to the pivot table "Percentage new in the first month" The formula should be [Count of First Month Customers]/ [Count of Customers]

How can I do this?

thank you
