Error While Calling A Procedure What is wrong in this procedure?

I have a table family:

Name          Null?    Type         
------------- -------- ------------ 
NAME          NOT NULL VARCHAR2(25) 
NICK_NAME              VARCHAR2(15) 
GENDER        NOT NULL CHAR(1)      
AGE           NOT NULL NUMBER(3)    
MARITL_STATUS NOT NULL VARCHAR2(15) 
QUALIFICTN    NOT NULL VARCHAR2(20) 
NO_OF_CHLDRN           NUMBER(2) 


I have created a procedure to insert values in this table. The procedure is compiled and created successfully:

create or replace procedure "insert_family"    
(NAME varchar2 ,
NICK_NAME varchar2 ,
GENDER VARCHAR2,
AGE number,
MARITL_STAUS varchar2,
QUALIFICTN varchar2,
NO_OF_CHLDRN number)    
is    
begin    
insert into family values(NAME,NICK_NAME,GENDER,AGE,MARITL_STAUS,QUALIFICTN,NO_OF_CHLDRN);    
end;   


But when I try to call this procedure through:

BEGIN
insert_family('AYUSH','SHUKLA','MALE',12,'UNMARRIED','SCHOOL',0);
END;
/


It gives me this error:


  BEGIN 
  insert_family('AYUSH','SHUKLA','MALE',12,'UNMARRIED','SCHOOL',0); 
  END; 
  Error report - 
  ORA-06550: line 2, column 1: 
  PLS-00201: identifier 'INSERT_FAMILY' must be declared 
  ORA-06550: line 2, column 1: 
  PL/SQL: Statement ignored 
  06550. 00000 -  "line %s, column %s:\n%s" 
  *Cause:    Usually a PL/SQL compilation error. 
  *Action: 


The problem seems to be in procedure as there is no parameter shown to
have values in debug mode:
When you create an object in Oracle with double quotes, Oracle creates that objects with the same case as you entered it. Try dropping the "insert_family"   procedure and creating it without the double quotes.

This should help.

SQL&gt; CREATE TABLE family
  2       ( NAME          VARCHAR2(25),
  3         NICK_NAME     VARCHAR2(15),
