In your destination field you want to use VLOOKUP like so:
=VLOOKUP(Sheet1!A1:A100,Sheet2!A1:F100,6,FALSE)
VLOOKUP Arguments:
- The set fields you want to lookup.
- The table range you want to lookup up your value against. The first column of your defined table should be the column you want compared against your lookup field. The table range should also contain the value you want to display (Column F).
- This defines what field you want to display upon a match.
- FALSE tells VLOOKUP to do an exact match.
