 tooltip = "Please Enter Customer number then click Customer Name"
 on user input

 temp = Customers [Customer_Number == input.Customer_No];
 input.Customer_Name = temp.Name;
 input.Plot_Number = temp.Customer_Plot_no;
 input.Address = temp.Cust_Address;
 input.E_mail_I_D = temp.Customer_Email;
 input.Phone_number = temp.Customer_Phone;
