How to count value in Crystal Report with Winforms C#.

I am using Crystal Report in Winforms with C#.

My Output Like :

StudentID   Name   1   2   3   4   5

    1        a     P   P   P   A   P
    2        b     A   P   A   P   A
    3        c     P   A   A   P   P
    4        d     A   A   A   P   A

But I want to Output Like :

StudentID   Name   1   2   3   4   5   Present   Absent

    1        a     P   P   P   A   P      4         1
    2        b     A   P   A   P   A      2         3
    3        c     P   A   A   P   P      3         2
    4        d     A   A   A   P   A      1         4
    
    -       Pre.   2   2   1   3   2
    -       Abs.   2   2   3   1   2

So how i can count this.

Thanx in Advance...
