=IF(ISNA(VLOOKUP(A1,Sheet2!A1:B4,2,FALSE)),"",
VLOOKUP(A1,Sheet2!A1:B4,2,FALSE))

See if this is what you are after. (this looks at the cell contents of A1
which is your , it then looks in sheet 2 for the range of data you
want to search, then returns the 2nd column in that range (the 434). The

Hi Guys,

I need your help, and I hope I'll make myself clear. So, I have to
workshhets. In sheet A there is a database, and one of the columns consists
of different email addresses. In sheet B, there is another database, and one
of the columns is again containing email addresses. Some of them match with
the column from sheet A. Now on sheet 2, to each email address corresponds a
certain PIN number. What I want to do is: search if each of the email
addresses from Sheet A is found on sheet B, and if it is, then I want to
return in a cell the PIN number corresponding to it.

sheet A sheet B

434
545
655
434

So, in the above example, I need to see if appears in the column
from sheet B, and then to return the # 434 in a cell next to the entry from
sheet A.

I hope I made myself clear enough. Help please!
