Distinct count summary output in a list

[lifzgud]

Hi i am preparing a list report
I have grouped a few columns
eg A ..then B..then C..eg if two divsion nos are identical they will be grouped but if two region nos are identical but divsion nos are not they will not be grouped..
A    B    C
1    2     A
      3     B
2    2      A
I need a distinct count on B.but when i'm doing a count on B its format is getting inconsistent because of the grouping,.plz help
