array formula(s)- not working, need some help please (problem with an 'AND')

[KR]

Column AA= numeric count of program participation
Column D= list of manager names (name repeats on each line)
Column G= list of employees by manager (plus one blank cell for
manager/self)
Column J = exclusion criteria

basically I'm trying to get a sum of how much participation has occurred in
each manager's area, without including that manager's participation, and
only for people without exclusion criteria- so I need to sum the values in
AA once per manager, excluding rows where Column G is blank or Column J is
not blank.

I got as far as this first array formula, which works to sum up everything
for that manager, but includes the manager's row, and sums regardless of
exclusion criteria:
'using IF(AND(D3<>D2,LEN(D3)>0),<stuff>,"") to only show the total once
per manager name

{=IF(AND(D3<>D2,LEN(D3)>0),SUM(IF(D$3$3000=D3,AA$3:AA$3000,0)),"") }

However, I still need to only count rows with employee names, and exclude
those that should be excluded, so I tried to add the exclusion criteria
first, and can't get it working:

{=IF(AND(D3<>D2,LEN(D3)>0),SUM(IF(AND(D$3$3000=D3,J$3:J$3000=""),AA$3:AA$3
000,0)),"") }

something about adding the AND formula makes my result zero, even when I
know there should be some value returned.

--> AND(D$3$3000=D3,J$3:J$3000="")
I would think that this would check each row one at a time, for example,
include AA5 in the sum only if D5=D3 /and/ J5 <>""

but now I'm starting to think that isn't how it works....
I'd appreciate any clarification on how to build this type of multiple
criteria into an array formula.

Thanks!

Something along the lines of

=IF(AND(D3<>D2,LEN(D3)>0),SUMPRODUCT(--(D$3$3000=D3),--(J$3:J$3000=""),AA$
3:AA$3000)),"")


just add more conditions like

--(range, test_against)

This is not an array formula

You might want to consider using the sumproduct formula. Let's say your data
is in rows 1-100. Try this

=SUMPRODUCT((A1:A100),--(D1100="Name"),--(G1:G100<>""),--(J1:J100<>""))

Oops, the formula should be

=SUMPRODUCT((AA1:AA100),--(D1100="Name"),--(G1:G100<>""),--(J1:J100<>""))

Bob and Barb-

Thank you for pointing me to the sumproduct formula. I think it will give me
what I need, but I saw that both of you include a double negative (--) in
front of your secondary conditions. I didn't see anything about that in the
helpfile- I'm assuming that prevents some other potential problem with the
formula....can you enlight me as to what that prevents or achieves? Just to
make sure I don't accidently mess it up ;-)

Thanks!!

simply put, the test

(D$3$3000=D3)

returns an array of TRUE/FALSE values. Performing an arithmetic operation on
it transforms this to an array of 1/0 values, which SP can use to multiply
by the actual values to get only the values where a condition is met. So a
single unary, -, transforms the TRUE/FALSE to 1/0, but a negative 1. So a
second is required to get it back to positive 1.

Thee is a lot more detail at

You can accomplish the same type coercion without the "--" by directly
multiplying the conditions together, as in

SUMPRODUCT( (D$3$3000=D3)*(J3:J$3000="") ,AA$3:AA$3000)

This approach extends naturally to more complicated combinations of
conditions, since "+" corresponds to "OR" just as "*" corresponds to "AND".
Moreover operator precidence is the same for Booleans as in regular
arithmetic, so it should be clear where additional parentheses are needed in
expressions of this type.

When you say + corresponds to or you MAY want to add that under certain
circumstances you will need to compare the or result (to something along the
lines of > 0) Otherwise you may end up with an overstated amount. The reason
I say this is that when I was first learning about +, all of the examples I
saw used it as Or and I assumed it was completely interchangeable until I
started seeing other posters adding a condition (to posts where I used it
without adding a conditon.) It wasn't until then that I realized the
potential for overstating the amount.
