Problem with Conditional Page Process

Question

Application Express 3.1.0.00.32
I have a conditional page process that whenever a user clicks on the create or save button, certain values are stored in one table and certain are stored in another dependent on the value of a page item.
If a user opens a record and makes a change to the entry but doesn't change the current status, the information saved differs from when the current status is altered. Since the code, syntaxically, is correct, I'm more incliendeid to think this is an APEX issue however here is the code:
declare
  v_current_status  pls_integer;
begin
  select fk_lov_status_id
    into v_current_status
    from com_status
   where fk_proj_master_id = :P23_CS_FK_PROJ_MASTER_ID
     and pk_com_status_id = (select max(pk_com_status_id) from com_status);
if v_current_status = :P23_FK_STATUS_ID then
  null;
  elsif (:P23_STATUS_COMMENT is null) then
    INSERT into com_status
      (fk_lov_status_id,
      fk_proj_master_id,
      status_comment)
    VALUES
      (:P23_FK_STATUS_ID,
      :P23_CS_FK_PROJ_MASTER_ID,
      'An update was not made to the status description.');
    commit;
  elsif (:P23_STATUS_COMMENT is not null) then
      INSERT into com_status
        (fk_lov_status_id,
        fk_proj_master_id,
        status_comment)
      VALUES
        (:P23_FK_STATUS_ID,
        :P23_CS_FK_PROJ_MASTER_ID,
        :P23_STATUS_COMMENT);
      commit;
  else
    null;
  end if;
end;Condition Type is: Request is Contained within Expression 1 for the values of the push buttons (SAVE,CREATE)
When Button Pressed is not conditional.
When running the page, the error ORA-01403: no data found is given.
In debug, the last couple of lines are:
0.06: Processing point: AFTER_SUBMIT
0.06: ...Process "Process Row of PROTRAC_MASTER": DML_PROCESS_ROW (AFTER_SUBMIT) #OWNER#:PROTRAC_MASTER:P23_PK_PROJ_MASTER_ID:PK_PROJ_MASTER_ID|IUD

Any ideas would be appreciated.

Here is the debug log after changing the status and not inputting any information in the description:
The description isn't reporting as %null% even though the page item is empty, it is reporting as "".
