Sum every Third Row

[Arlan]

I have a spreadsheet that is created via an Access database. I am
inserting a Recordset, then inserting some blank rows after each row
of data with formulas. I now need to SUM every third row, Column C,
starting at Row 8....an example is below. Every ROW that has DIFF:
needs to be summed at the end of the spreadsheet...any ides would be
appreciated...Thanks

=SUMIF(A2:A1000,"Diff",B2:B1000)

Is this what you want

=SUM(IF(MOD(ROW(1:2000),3)=0,c1:c2000)). It will sum every third row in
column C. It is an array formula and must be commited with Ctrl + Shift +
Enter or it will return zero.

But it is not necessary if indeed the OP want to sum one column for each
"Diff" in another column?

Yes, I thought your solution would probably be correct, but the data looked
as if it might be in one column.
