I think something like this will do it, entered as an array formula with
Ctrl+Shift+Enter:

=IF(OR(C1=LARGE(--(B1=$B$1:$B$8)*($C$1:$C$8),1),C1=LARGE(--(B1=$B$1:$B$8)*($C$1:$C$8),2)),1,0)

This is my example €“ and I want to find a way to simplify the calculations
because I have a list of more than 1800 rows! �

I want to write a conditional function that result in something like this:
on C1 I want to say that if B1 is the 1st or 2nd largest number of the
€œLisbon group€� (which has 5 rows) it should write 1, otherwise 0, on C2 I
want to say that if B2 is the 1st or 2nd largest number of the €œLisbon group€�
(which has 5 rows) it should write 1, otherwise 0€¦ and so on€¦

And I want to apply the same condition on €œParis group€� which has 3 rows€¦

Thats why I was trying to use the VLOOKUP function €“ I pretend to €œsay€�
that on the range of numbers associated to Lisbon please tell me if B1 is the
1st or 2nd largest number€¦

I am not sure if I explained myself quite well€¦ I tried to simplify the
example€¦

Thanks anyway for your help!

For the nth number you need to compare it agaisnt other numbers. As is
you're not doing that for anything other than the largest value which is a
1:1 comparison. If you're looking for the 2nd largest value then you need at
least a 1:2 comparison.

You need to replace VLOOKUP with something that returns an array of numbers.
VLOOKUP returns just a single element which is why the LARGE(...,1) works.
It's a 1:1 comparison.

Need a more detailed explanation to figure out what to suggest.

I am trying to use LARGE function with VLOOKUP function and except for the
case where k=1, I am getting a "#NUM!" message.

The idea is to use a conditional function (like IF) and the logical test
is
to evaluate if certain number is 1st, 2nd or 3rd of a group of values. But
the group of values is not "stable", i.e. the number of arguments to
compare
with varies according to a text criteria. That's why I am using the
VLOOKUP.

So, the formula I used is the following:

=IF(F12=LARGE(VLOOKUP(D12,$D$12:$F$30,3,FALSE),1), 1,0)

Column F has numbers
Column D has text

Does anyone have an idea how to solve this?
