Hello,
I need to add the odd columns (A,C and E) and put the result under Total in
and add the even columns (B,D and F) and put the result under Total out
I have to use MOD function .... thanks

I've tried ( =SUMIF(A2:F2;MOD(COLUMN(A2);2)<>0;A2:F2) ) but it's not working?
could you please fix my formula? thanks
