If intervening cells are blank: =SUMPRODUCT(D3:D7,G3:G7) 3. If intervening cells need to be skipped: =SUMPRODUCT(--(MOD(ROW(D3:D7),2)=1)*D3:D7*G3:G7) -- Max Singapore http://savefile.com/projects/236895 xdemechanik --- |

The 3rd option should read simply as:
=SUMPRODUCT((MOD(ROW(D3:D7),2)=1)*D3:D7*G3:G7) (no need for the preceding: "--") -- Max Singapore http://savefile.com/projects/236895 xdemechanik --- |

Thanks Max. I actually figured it out just before your reply came through; I
did it with the first option you listed. I have a much harder one I am trying to figure out now. I have figured out the formula to get the sum from 31 sheets on to a summary sheet at the end of the Excel book; EX: =SUM(1:31!J3:J8). However, I now need to know how to do it with an exception. Ex: I need =SUM(1:31!P3:P8) BUT ONLY IF THE FIGURES IN P3:P8 ARE POSITIVE. Then I need, for another cell, =SUM(1:31!P3:P8) BUT ONLY IF FIGURES IN P3:P8 ARE NEGATIVE.
