Inserting Values in a Cell Depending on Content in an Adjacent Cell

Hi, this is a little more complex than the title but I wasn't able to phrase it succintly enough.

I have the names of companies in one column, and the amount they owe in cells in the column beside them. I then have a second list of companies that is a subset of the first. Is there a formula that would place the amount they owe in teh corresponding cell adjacent to the compny in the second list? I've attached a sample workbook, Full Company List in column A, amount owing in B, trimmed down list in D and ideally I'd like the corresponding values in E. Thanks in advance!

Perfect! Thank you very much.
