WOW, Great....Claus, Thanks you made the solution.. Though I need to learn on the Sum Product Function as well as MOD Function..... As I am not clear that why divisor is 3... If you can Explain.

you want check every 3rd column. Therefore you have to divide the column
number by 3.
MOD(COLUMN(B3:CR3),3)=2
is true for columns 2, 5, 8, 11 and so on.
