Need help on running methos in Forms 6i

Question

When I was trying to run a methods from Forms 6i Iget this message
PDE_PSD001 Could not resolve reference to <unknown program unit> while loading block
PO_05_aug
In SQL I run the following code:
CREATE OR REPLACE TYPE T_PERSONA AS OBJECT
(NOMBRES CHAR (20),
APELLIDOS CHAR (20),
FECHANACIMIENTO DATE,
MEMBER FUNCTION NOMBRECOMPLETO
RETURN VARCHAR2,
MEMBER FUNCTION EDAD
RETURN VARCHAR2);
REM
CREATE OR REPLACE TYPE BODY T_PERSONA IS
MEMBER FUNCTION NOMBRECOMPLETO
RETURN VARCHAR2
IS
BEGIN
RETURN RTRIM (NOMBRES) | | ' ' | | RTRIM (APELLIDOS);
END;
MEMBER FUNCTION EDAD
RETURN VARCHAR2
IS
DD DATE;
DIAS INTEGER;
MESES INTEGER;
ANIOS INTEGER;
BEGIN
SELECT SYSDATE INTO DD FROM DUAL;
DIAS := DD - FECHANACIMIENTO;
ANIOS := TRUNC (DIAS / 365);
MESES := TRUNC ((DIAS - (ANIOS * 365)) / 30);
DIAS := DIAS - ANIOS * 365 - MESES * 30;
RETURN ANIOS | | ' ANIOS, ' | | MESES | | ' MESES, ' | | DIAS | | ' DIAS';
END;
END;
REM
CREATE TABLE EMPLEADO
(DATOS T_PERSONA,
SUELDO NUMBER);
REM
CREATE TABLE PROFESOR
(DATOS T_PERSONA,
SUELDO NUMBER,
HORASEXTRAS NUMBER);
INSERT INTO PROFESOR VALUES
(T_PERSONA ('FRANCISCO', 'VILLAVICENCIO','27-12-1951'),
1000, 400);
In Forms, when compiling in a buttom trigger the code:
declare
edades varchar2(20);
begin
SELECT A.DATOS.NOMBRECOMPLETO () into edades
FROM PROFESOR A;
message (edades);
end;
I get the message
PDE_PSD001 Could not resolve reference to <unknown program unit> while loading block
PO_05_aug.
In SQL it runs OK:
SQL> SELECT A.DATOS.NOMBRECOMPLETO () FROM PROFESOR A;
A.DATOS.NOMBRECOMPLETO()
FRANCISCO VILLAVICENCIO
Does any one help me?
