Count Issue

[#1]

Hi,

my date looks like below

Customer Old Grade New Grade

ABC               1                    2

DEF               1                    2

XYZ                1                    3

MNO              1                    4                        

Pqr                 2                   1

so on....

now my issue is I need a pivot table with columns old grade, new grade and count of customers  where grading has been switched from old grade to new grade..

my result should look like

                             New Grade    

                              1              2             3         ............

old grade       1         2 -------->( here count 2 is there are two customers (ABC,DEF) whose grading has been moved from 1 to 2).

Plesase note : I'm ok if the results can be achieved using anyother chart.

Any help is highly appreciated.
