How can I set default value in a field based on a LOV?

Question

Here's the LOV:
select txtName, ID
from FAC_LK_PROJECT_PRIORITY
order by 1
I tried:
select id from FAC_LK_PROJECT_PRIORITY priority where txtname = 'Medium';
and set the default value type to be PL/SQL function body but that didn't work - I get this error:
ORA-06550: line 2, column 1: PLS-00428: an INTO clause is expected in this SELECT statement
Error ERR-9131 Error in PLSQL function body for item default code, item=P19_PRIORITYID
OK
The item is a select list w/ db column as source: PRIORITYID

Hi Scott. thanks for answering. I get from your post that I need to declare a variable and then return something. I changed it to this
declare v_id number := null;
begin
  select id into v_id
      from FAC_LK_PROJECT_PRIORITY priority
      where txtname = 'Medium';
  return v_id;
end;and it works.
Why do you use a loop? In case there's >1 row returned by the query?
