Find value in row and retrieve adjacent cell

Hi Everyone,

I'm having a problem that has been plaguing me for some time.

I have a spreadsheet of Years, with the cost associated with each year for each particular entry (row). Each row has a different set of years in each column, but I am looking to return the amount for a specified year in just one column at the end.

Before I confuse you more, maybe the attached spreadsheet will help explain.

Lookup in Array.xlsx

I have manually populated Column L to illustrate what I am trying to do. Does anyone happen to know a formula that can do this?

Happy to answer any questions if I can help clarify.

Thank you.
