I have a file that includes several sheets. On the first sheet, I am trying
to pull in total requirement quantities for part numbers based on the date
which are located on another sheet.

This is the formula that I am using
=SUMIFS('Material needed for open orders'!$D$3:$D$401,'Material needed for
open orders'!$A$3:$A$401,'Raw Material Planning'!$B2,'Material needed for
open orders'!$C$3:$C$401,"'Material needed for open orders'!$O$1",'Material
needed for open orders'!$C$3:$C$401,"<='Material needed for open
orders'!$P$1")

My first sheet looks like this

20843 10043 50000 14701 35299 15.2 0.0

My second sheet is this

Columns O & P referenced in the formula are date fields to show weekly
buckets. I can get the formula to work properly without using the dates, but
when I add the date criteria, all of my totals are 0.
