Formula to sum every 4th cell returns #DIV/0! error in some column
 

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

Do you mean a #VALUE! error? If so, then it's likely that your range of
cells contains one or more text values. Maybe your range contains
formula blanks. Try the following syntax instead...

=SUMPRODUCT(--(MOD(ROW(E7:E190)-ROW(E7),4)=0),E7:E190)

....which ignores text values, including formula blanks.

Hope this helps!

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

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.

In that case, try the following formula...

=SUM(IF(MOD(ROW(E7:E190)-ROW(E7),4)=0,IF(ISNUMBER(E7:E190),E7:E190)))

....confirmed with CONTROL+SHIFT+ENTER, not just ENTER.

Hope this helps!

An alternative is to have your formulas return 0 or blank instead of
#DIV/0!. If you have your formulas return a blank, you can use the
first formula I offered...
