Hi Ardus,

Thanks for giving attention to my problem but when i am using this formula
getting an value error and i am not so familier with excel formulas so dont
can understand how this formula actually works, this formula looks so
complecated to me,will you help me again to resolve the problem,

thanks again for replying,

My formula is based on current row number. If row id odd, add the number,
else skip it.

Do you get a #VALUE result?

One or more of the cells in your sum range is probably producing the #VALUE!
error, which is being mirrored (returned) by Ardus' formula.

Make sure there are no errors in your original data.

To sum even row numbers: ( A2,A4, A6,...)
=SUMPRODUCT(--(MOD(ROW(A1:A99),2)=01),A1:A99)

To sum odd row numbers: (A1, A3, A5, ...)
=SUMPRODUCT(--(MOD(ROW(A1:A99),2)=1),A1:A99)
