Sorting section based on the their values

Hi All,

In one of my report, I have put break on one column and it is shorting based on that column. but as per my req. which ever section is having high count it should display that sction first.

example:

Channel     Code               Revenue     Sum

DMAXA22     D20401          10               10

                      D20402          20               20

                      D20403          30               30

sum                                       60               60

FTSX000     D21402          50               50

                    D21403          60               60    

                    D21404          100               100

Sum:                                  210              210

In above expample, I need "FTSX00" sction should come up and other one should come down.

Thank you..
