Dear sir,
I tried Sum Product which is Multiple Text and date Criteria and i did not get the correct answer. could you please correct this formula..

=SUMPRODUCT((C7:C450=X7)*((--$B$7:$B$450<=AC3)*(--($B$7:$B$450>=Z3))*(G7:G450=Z6)*(M7:M450)))..



B column is Date
C column is Name..
G column is Grade..
M column is Value..
I would like sum the M column..more important any two dates between the dates..

Try this:

=SUMPRODUCT(--($C$7:$C$450=X7), --($B$7:$B$450<=AC3), --($B$7:$B$450>=Z3), --($G$7:$G$450=Z6), $M$7:$M$450)


That should work, if it doesn't, you're probably having a "matching" error with the dates, perhaps caused by formatting issue that AC3 and Z3 aren't the same format as you column B dates.
