I think Bob's formulas are supposed to contain commas, not semicolons, as such:
=SUMPRODUCT(--(MONTH(A1:A10)=4),--(B1:B10="criteria"),D1:D10)

Also, you may consider this:
=COUNTIF(A1:A9,"=4")+COUNTIF(B1:B9,"criteria")

However, that may not yield the results you are after.

Finally, a pivot table would do it for you, but I think you'd have to add a
helper column, and you have to use something like the =month() function.

MONTH=4? MONTH of what?
Did you look in Help for the usage of MONTH?

Hi.

I have a table of entries, structured in the following way:

Column A contains dates. Column B contains a data validated list. Column D
contains values.

I now wish to go through all the rows in the list, and sum the values if
1)
the value of the cell in column B matches "criteria", and 2) the date in
column A is in a specific month.

I tried the following formula to sum over all dates in April, without
success:

=SUMIFS(D1:D10;A1:A10;MONTH=4;B1:B10;"criteria")

I suspect my use of the MONTH function is a bit unorthodox, but can't seem
to figure out the proper way to do it.

I would greatly appreciate any help!
