Error calling data from a list to a registration screen

From now on Thank you for understanding everyone, as I am not very experienced. I am having an error loading client data from a list. I want, when I click on the add client, I get the client name in the client field and so with the salesperson and product. But when I click the add client button it opens the list screen, I give an onClickListner on the client line and it comes to the request screen without the client name in the client field
