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't use the whole column.

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))

I have a spreadsheet that has MFG #, Manufacturer, Description and Unit
Price. I need a formula that will look up and match at least the data in 3
columns (MFG #, Manufacturer and Unit Price) in another workbook and bring
back the quantity shipped for the row that matches that criteria. Can you
help with a formula? Maybe a combination of formula (if that's possible)
such as look up MFG #.... and if the manufacturer and unit price match, give
me the quantity shipped....

PLEASE help and let me know ASAP if you know the answer :o)....
