Answer 1

This code is just a sample from the Help documentation. It won't work until you modify it for your form.
Why do you have "steps" in your code? You are suppose to do what the steps tell you. You don't place the steps in your code. The steps must be removed from your code.
Step 1 code goes in a program unit, not in a trigger.
Step 2 and 3 code usually goes in a trigger.
You will have to replace the names of the items and record group with your own names as you have defined them in your form.
step 1: create a procedure in your application
procedure load_list(itm in VARCHAR2, rg in VARCHAR2) is
group_id RecordGroup := Find_Group(rg);
list_id Item := Find_Item(itm);
Begin
if Populate_Group(group_id)<>0 then
Message('Unable to populate record group');
Raise Form_Trigger_Failure;
end if;
Clear_List(list_id);
Populate_list(list_id, group_id);
end;
step 2: create a record group named rg_cat and assign Record Group Query to something like "select categoryname from category"
step 3: call this procedure as
load_list('categoryname','rg_cat');
