Pivot Table Calculation

[Silena K-K]

Hi everyone

I having difficulty with calculating fields in a pivot table. The scenario
I have is

I have the following set-up:
Data
Rel Month Product Name Count of Rel Month Avg Cycle Time
Jul-07 Isot 40 2
9
Jul-07 Total 2
9
Aug-07 Isot 20 6
12
Aug-07 Isot 40 1
20
Aug-07 Total 7
(forgot??)

etc...

What I need is a column in the pivot table to give me the avg cycle
time/product/month ie:

Jul-07 Isot 40 (Avg Cycle Time/Count of Rel Month) = 9/2 = 4.5
Aug-07 Isot 20 = 12/6 = 2
Aug-07 Isot 4 = 20/1 = 20

etc...

I tried adding a calculated field =Avg Cycle Time/Count Rel Month but I got
really weird figures.

Thanks so much, Silena
