Sumif withdates

[Guest]

I am trying to check a column of dates and if that column corresponds with
the critera (in other words if the dates match), I want it to add the invoice
values together. I can't get it to work, it returns the result zero all the
time? Can anybody help. What am I doing wrong?
E.G. I want excel to check the dates under the payment due column (RANGE)
and if any date matches the date under the criteria column i then want it to
add the invoice values together. Working example is, check payment dues dates
and if any match criteria 01/06/2007 then add the values together, so there
are 2 instances of date 01/06/2007 so excel should add the corresponding
values together i.e.15.25+845.00

payment due invoice value RANGE
SUM VALUE

01/06/2007 15.25
01/07/2007 26.00
01/08/2007 56.00
01/06/2007 845.00
01/07/2007 2256.33
01/08/2007 45.23


CRITERIA Jun Jul Aug
01/06/2007 0.00 0.00 0.00
01/07/2007
01/08/2007

Trying to sum payments due jul here
Trying to sum payments due aug here

Assume source data within D2:E7, dates in col D, amts in col E

Assume you have 1st-of-month real dates (formatted as say: mmm-yy)
in D10:F10 as headers, viz: Jun-07, Jul-07, Aug-07

Then you could place in D11:
=SUMIF($D$2:$D$7,D$10,$E$2:$E$7)
and copy across to F11 to return the required sums below each month header
