Please, I need help on how to view the results of my zonal statistics. 
Hello Ahmed,
Based on the screenshot you provided, it appears that you are currently viewing the results in the attribute table, but in what's known as the "form view." If you wish to switch back to the "table view," please refer to the screenshot below.
Hope this clarifies things for you!
Best regards, Oualid
Thank you for your quick response.
