Hi,
Without a description of what your trying to do all that can be offered is
general help and I suggets this.
Start your formula manually with
=lookup(
and then navigate to the lookup value (say) a1 of sheet 1 and Excel will
correctly input the syntax of
=lookup(Sheet1!A1
manualy enter the comma and then navigate again to the lookup vector and
once again Excel will enter the correct syntax for that range. Carry on until
the formula is complete

When competing hypotheses are otherwise equal, adopt the hypothesis that
introduces the fewest assumptions while still sufficiently answering the
question.
