انا اعمل برنامج ولكن المطلوب هو عمل كمبوبوكس وليس list of value
تقراء من جدول كيف يتم ذللك

al salam alekom wa ra7mat allah wa brakatoh

you can fill a list by many ways may be by record group or by a cursor
this example by cursor.

in your case write the select statement from your schema

teka care the list consists from two things:-

1-in my example last_name will appear to the end user.
2-but when the end user select a name the value wich wll be inserted is employee_id.


if you want the user to select a name and submit a name so you to select only the last_name and write in the function both rec.last_name.


also u can know more about the function add_list_element fom the help.

declare 
       cursor  cursor_name is select employee_id,last_name
                                                   from employees;

  begin

   for  rec in cursor_name loop

add_list_element('the name of the list',1,rec.last_name,rec.employee_id);

  end loop;

end;

you have to choose a suitable trigger to this list
as
when new form instance
when new block
when new item

any trigger which helps i your case.
this is all i have now .if u have any thing else u can ask i will answer if i know insha2 allah.
