Saved from a previous post:
If you want exact matches for just two columns (and return a value from a
third), you could use:
=index(othersheet!$c$1:$c$100,
match(1,(a2=othersheet!$a$1:$a$100)
*(b2=othersheet!$b$1:$b$100),0))
(all in one cell)
This is an array formula. Hit ctrl-shift-enter instead of enter. If you do it
correctly, excel will wrap curly brackets {} around your formula. (don't type
them yourself.)
Adjust the range to match--but you can only use the whole column in xl2007.
This returns the value in othersheet column C when column A and B (of
othersheet) match A2 and B2 of the sheet with the formula.
And you can add more conditions by just adding more stuff to that product
portion of the formula:
=index(othersheet!$d$1:$d$100,
match(1,(a2=othersheet!$a$1:$a$100)
*(b2=othersheet!$b$1:$b$100)
*(c2=othersheet!$c$1:$c$100),0))
============
If there is only one match and you're bringing back a number (or 0 if there is
no match for all the criteria), you can use:
=sumproduct(--(othersheet!a1:a10=a1),
--(othersheet!b1:b10=b1),
(othersheet!c1:c10))
Or if you want to include the "router-1" in the formula:
=sumproduct(--(othersheet!a1:a10=a1),
--(othersheet!b1:b10="router-1"),
(othersheet!c1:c10))
Adjust the ranges to match--but you can't use whole columns (except in xl2007).
=sumproduct() likes to work with numbers. The -- stuff changes trues and falses
to 1's and 0's.
Bob Phillips explains =sumproduct() in much more detail here:

And J.E. McGimpsey has some notes at:

===========================
So in your example, you may want something like:
=index(othersheet!$j$1:$j$100,
match(1,(a2=othersheet!$a$1:$a$100)
*(b2=othersheet!$c$1:$c$100)
*(c2>=othersheet!$g$1:$g$100)
*(c2<=othersheet!$h$1:$h$100),0))
Where the current sheet has:
qtr in A2 (exact match)
so in B2 (exact match)
date in C2 (where C2 >= effective date and at the same time <= end date)
(remember, it's still an array formula.)
