Excel add amounts that meet criteria

I have a workbook with two sheets (sheet 1 and sheet 2). On sheet 1 I have company names in column A. The names only appear once.  On sheet 2 column A, I also have company names and the company names can appear more then once.

I need a formula in sheet 1 column b that looks at sheet 2 and matches the company name in column a. If the name mach, add the amounts from sheet 2 column S to sheet 1 column b.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
