Trying to count the # times that 3.25 shows up in rows that meet multiple
criteria.

I've got this formula working with 2 variables:
=SUMPRODUCT(--($B$9:$B$16=3.25),--($D$9:$D$16="1001"))

But I want to add another and that seems to foul it up (returns 0, instead
of the correct count #). My last two criteria are to limit it to within 30
days of a date. Any ideas what I have wrong here?
=SUMPRODUCT(--($B$9:$B$16=3.25),--($D$9:$D$16="1001"),(--($A5-($A$9:$A$16))<30))
