The following formula...

=SUMPRODUCT(--ISNUMBER(MATCH(G8:G14,pl_Resources,0)),--ISNUMBER(1/(LOOKUP
(G8:G14,pl_Provider)="Yes")),M8:M14)

....seems to fail when any one of the array of lookup values returns a
#N/A value. Therefore, wouldn't the following formula be more
appropriate?

=SUM(IF(ISNUMBER(MATCH(G8:G14,pl_Resources,0)),(LO OKUP(G8:G14,pl_Provider
)="Yes")* M8:M14))

....confirmed with CONTROL+SHIFT+ENTER.

I assume that:

(1) pl_Resources refers to the first column of pl_Provider,
(2) pl_Provider is set (sorted) in ascending order on pl_provider.

[A] If G8:G14 is guaranteed not to contain any item that does not also
exist pl_Resources, then:

=SUMPRODUCT(--(LOOKUP(G8:G14,pl_Provider)="Yes"),M8:M14)

If Yes/No values are not in the last column of pl_Provider...

=SUMPRODUCT(--(LOOKUP(G8:G14,pl_Resources,INDEX(pl_Provider,0,3) )="Yes"),M8:M1
4)

[b] If G8:G14 might contain items that do not exist in pl_Resources, then:

=SUMPRODUCT(--ISNUMBER(MATCH(G8:G14,pl_Resources,0)),--ISNUMBER(1/(LOOKUP(G8:G
14,pl_Provider)="Yes")),M8:M14)

I could use some help determining my problem with a Sumproduct function.
I'm wanting to sum a list "M8:M14" if a criteria is met. Here's where
I'm getting in trouble.
I have a separate database or multi-row/multi-column array
(pl_Provider) with the first column a listing of items and in the third
column of the array I have assigned a value of "Yes" or "No" in the same
row for each item.

I'm having the formula look at a local range "G8:G14" and then do a
lookup in the array "pl_Provider" to determine if a Matching record
from column G exists and if it does to return the value from column 3,
"Yes" or "No". If it is Yes, I want to include the value in column M
in the sum.

=SUMPRODUCT(--(INDEX(pl_Provider,
MATCH(G8:G14,pl_Resources,0),3)="Yes"),(M8:M14))

The first array in Sumproduct doesn't seem to be giving me an array
value, but seems to only evaluate it for only the first value. What
don't I understand???
