VLOOKUP formula error message

Hi ,

I need help with the VLOOKUP formula .

I have a VLOOKUP formula that works from one sheet to another. I am confused as I get: '# Incorrect Argument Set' as an error.

=VLOOKUP({Code livrable}; {Planning actualisé / plage}; 10;false)

The below is the formula :

{Code livrable} is the first column range

{Planning actualisé / plage} is the table range in which we have to pick up data from the 10 th column

Can we help ?

Thanks in advance .
