Hi Hammer:
One method is to use the sumproduct formula as shown below.
=SUMPRODUCT(--(MONTH($B$3:$B$8)=10),$H$3:$H$8)
+=SUMPRODUCT(--(MONTH($B$3:$B$8)=10),$I$3:$I$8)
+=SUMPRODUCT(--(MONTH($B$3:$B$8)=10),$J$3:$J$8)
+=SUMPRODUCT(--(MONTH($B$3:$B$8)=10),$K$3:$K$8)
This method is not very easy to maintain so add a helper column to give the
sum and then just do the sumproduct on the helper column.
You can also replace the 10 with a link to cell.
