Ok, now I'm not following you.

You said:

have Availability date between D1 and D2.

Assume D1 = start_date and D2 = end_date

Then:

.....)*(date_range=D1)*(date_range<=D2)...

date_range is the range on Sheet2 that holds your dates.

Right. But I don't know how to get a hold of the date.

How do I write "find in Sheet2 a line that matches the given item in
Sheet1
and verify the date in Sheet2 sits between a date range"?

I attempted to write the first part of the question like
(isnumber(match(Sheet1!A1:A100,Sheet2!A1:A50,0))).

How do I write the lookup for the date in Sheet2?

Thank you.

I am looking for a sumproduct formula that counts how many Titles in a
sheet
are Backordered and have Availability date between D1 and D2.
The data resides in two separate sheets:

Sheet1
=====
Title1 InStock
Title 2 Backorder

Sheet2
=====
Title2 03/15/08

The formula would be something like:
=sumproduct((Sheet1!A1:A100="Backorder")*(isnumber (match(Sheet1!A1:A100,Sheet2!A1:A50,0))).
and here is where I don't know how to further check the date associated
with
a given item.

Thank you.
