Sam,

Unfortunately, WEEKNUM will not return an array, don't know why, it is just
implemented that way.

This should work for you though

=SUMPRODUCT((1+INT(($A$87:$A$452-(DATE(YEAR($A$87:$A$452),1,2)-WEEKDAY(DATE(
YEAR($A$87:$A$452),1,1))))/7)=A1)*(B$87:B$452))

Hello Friends

I've got the dates of the year (mm/dd/yyyy) in col A from row 87 to 452.
I've got the number of employes I used on that date next to the date in
col
B. What I want is to have 1-52 in Col A at the top of the sheet and the
number of employees I used in that week of the year across from the
corresponding number in Col B. I've tried
=SUMPRODUCT((WEEKNUM($A$87:$A$452)=A1)*(B$87:B$452 )) but keep getting a
#VALUE! error.

Thanks for any and all help. I appreciate your being there!

Sam
