I have a column of 5 digit numbers, the first 3 digits are an item code and
the last 2 identify which customer it is going to. In an adjacent column I
have the quantity of the product is being pulled by the customer.

How do I lookup the last 2 digits, to identify the customer, and get the
quantity that is being pulled without having to go through the sheet of
hundreds of different orders?

I am stuck.
