I have been trying to search for the answer but can't quite find it. I am
trying to do what I can only think of to call a two level lookup. Basically
it requires to pieces of data to uniquely identify the record.

In the example below I will have a record that contains a business unit and
an account next to each other. I want to look back at another worksheet to
pull the amount.

Business Unit Account Amount
00001 9000 $5
00002 9000 $10
00002 9001 $2
00002 9002 $13
00003 9002 $8
00003 9003 $21


So for example if I had another worksheet set up with the following.

00002 9002

how do i pull the value $13? For simplicity sake we can assume the upper
right hand value of '00001' is in cell A1.

Thanks to anyone with any advice.
