Hey Tom,

Yes, in some of the colums the cell with this formula displays #DIV/0!, in
other columns I get the desired sums. All the cells with this formula are in
the same row (row 198) and refer to data in rows 7 - 195..

Thanks for your interest and help.

do the columns have cells returing a #DIV/0 error?

I use this formula to sum the values in every fourth cell in colums
=SUMPRODUCT((MOD(ROW(E7:E190),4)=3)*(E7:E190)). This works in about half of
the colums, but returns the error #DIV/0! in the other colums. I do not get
why I get the error only some of the time.

What causes this and how do I correct it?

Thanks
