Hi,

My requirement is need to get the count of Break down for Calendar Year/month.

But the above screen shot if u look up for the month of "Jun 2013" i have 2 count,but the Last Column is " Count " shows as "2"

Actually i need to use only Calendar Year/Month ..If i use remove the " Calendar Day" Last Column for the month Jun shows as "1"

I want o/p must be

Calendar Year/Month   Count  Line

apr 2013                         2   Line 1

mar 2013                        5   Line 2

how it is possible to get the correct count.
