Pivot table formula with "show data as" value
 

Hi,
I have two columns in a pivot table with data in time order and they are
showed as 'Running total in' - base field 'Month'.
I would like to have a result in the pivot table to have the ratio of one to
the other in each month with the 'Running total in' values.
Is it possible ?

Thanks,

Zsuzsi
