error- column not allowed here & too many values upon insert - sql

Question

I have this new problem after creating the Subscriber table of Subscriber_T type and its function i cant seem to insert any value in Subscrber table. The error, i keep getting is column not allowed here. But where???
These are the scripts and an insert record.
CREATE OR REPLACE TYPE Surnames_T AS OBJECT (
Surname varchar (20)
);
/
CREATE OR REPLACE TYPE listSurnames_T
AS Varray(4) of Surnames_T;
/
CREATE OR REPLACE TYPE listTels as object(
Tel number (12)
);
/
CREATE OR REPLACE TYPE listTels_T as Varray(5) of listTels;
/
CREATE OR REPLACE TYPE ADDRESS_T AS OBJECT (
NUM number (6),
STREET varchar (20),
TOWN varchar (20)
);
/
CREATE or replace type TAddress
as table of Address_T;
/
create or replace type Subscriber_T as object(
num_s number(6),
sName varchar(30),
surname listSurnames_T,
Adds TAddress,
DateOfBirth date,
phoneNo listTels_T,
member function Age return number
);
/
create table Subscribers of Subscriber_T(
CONSTRAINT subscriber_pk primary key (num_s)
)
nested table Adds store as Tab_Adds;
/
show errors
create or replace type body Subscriber_T as
member function Age return number is
calc_age number;
dob date;
diff date;
begin
select S.dateOfBirth into dob
from Subscribers S
where deref(S.num_s) = self
diff := sysdate - dob
calc_age := to_Char(diff, 'YYYY')
return cal_age;
end;
end;
/
show errors
insert into Subscribers values (34, Chloe, listSurnames_T(Surnames_T('Dave'), Surnames_T('Camille'), Surnames_T('Jones')),
TAddress(Address_T(10, 'ave Foch', 'Ravenwood'), Address_T(30, 'rue des pole', 'England')),
'10-11-1976',
listTels_T(listTels(5839550456), listTels(6834734567)));
I'm guessing the function is raising this problem but it shows no error on compilation.

Answer 1

Some issues:
You don't need to do a SELECT in the member function age.
You haven't quoted the name Chloe so its not a string.
You haven't converted the '10-11-1976' to a date.
You should not use VARCHAR as a datatype - use VARCHAR2 instead.

Query 1:
SELECT s.age() FROM subscribers s
Results:
| S.AGE() |
|---------|
| 37 |
Edit
I'm not sure why you are wrapping a VARCHAR2 in the Surnames_T type or a NUMBER in the ListTels type. You can omit these and just do:
CREATE OR REPLACE TYPE listSurnames_T
AS Varray(4) of VARCHAR2(20)
/
CREATE OR REPLACE TYPE listTels_T as Varray(5) of NUMBER(12)
/
and:
insert into Subscribers values (
34,
'Chloe',
listSurnames_T(
'Dave',
'Camille',
'Jones'
),
TAddress(
Address_T(10, 'ave Foch', 'Ravenwood'),
Address_T(30, 'rue des pole', 'England')
),
TO_DATE( '10-11-1976', 'DD-MM-YYYY' ),
listTels_T(
5839550456,
6834734567
)
)
