VLOOKUP range question

Hello,

=VLOOKUP(A4,OLD!$A1:$B1404,2,FALSE)

I'm using this formula in my spreadsheet and it is working EXCEPT
when the new spreadsheet has inserted enough rows that my target cell on spreadsheet 1 isn't included.

For example

OLD contains '4412' in Row 32 Col A
NEW contains '4412' in Row 41 Col A
and the formula is =VLOOKUP(A41,OLD!$A38:$B1441,2,FALSE)

Since 4412 is in Row 32, it isn't finding it because it doesn't start searching until A38.

Please help!

Thank you!
