Find a value in a column and extract the coresponding value

Hi again.

I have two columns, B25:B40 and C25:C40, both containing numbers.
I want to search for the A18 number in the C25:C40 column and return the associated B value.

So if A18 value is found to be equal with let's say C25 value, I want to return the B25 value.
If A18=C26 return B26, and so on.

Maybe try...

=INDEX($B$25:$B$40,MATCH($A$18,$C$25:$C$40,0))

You're most welcome
