literally I’m not understanding what I have to look for and how I have to look, I have read and re-read the question and the form, but I am unable to understand, can someone explain me better what to do??? Please, I’ve been behind this form for 3 days to no avail and no notions learned

Not sure if you figured it out yet, but if you ran the ns query it gave you the answer. I was stuck on this for about two hours myself.
