==================
Hello, everyone. 
I would like to construct a table with Array text Where the field Revenues 2022 (€/ha) is automatically filled by the product of Yield 2022 (q.li/ha) and Price 2022 (€/ha), as in example. And afterwards, when I add the value of Costs 2022 in Euro, the Cost 2022 % is automatically filled in % of Revenues, as in example. Let me know if this is possible and if so, how to do it. 
Thank you very much
 

Please, do not double post.
You asked this already in the Italian part.
