thanks that worked... do you know of anyway to have that work over multiple sheets in a workbook???
Not easily.
SUMIF is not a function that works with 3D references. And it would depend on
precisely how your worksheets are set up.
If dates are always in the same place on each sheet, you could somehow derive
that information from one worksheet, and then use SUM with the 3D reference.
If the date locations vary on each sheet, it would probably be simplest to use
a VBA routine.
Another option would be to have a summary area on a single worksheet, and then
use SUMIF in that area.
