Facing an issue to do calculation between two fields of two different pivot tables, because there is no common key.

The scenario is as below

First Pivot Table:                                                            Second Table

campaign Year         2013                      2014                   Subscribed Year      2013                 2014 

Camp Quarter        Q1   Q2 Q3           Q1 Q2 Q3                Sub Quarter        Q1  Q2   Q3       Q1  Q2   Q3

A1                         2      4    6              1   4     5                     A1             3    5      9          1    4     5

A2                         3       3    4             2   5     7                      A2             4    6      7           2    5    6

Output Should be Sum of values for particular quarter

Output Year           2013                      2014

                            Q1   Q2 Q3            Q1  Q2  Q3
