Question about Table Function inside a Package

Question

Hi … I am new in PL/SQL, I am trying to use a table function to create depending on a value passed to it (I am using 10g). Everything works great but the moment I add a parameter everything explode, I am creating it on a package.
SQL that work
CREATE OR REPLACE PACKAGE BODY financial_reports AS
FUNCTION Fund_Amount
RETURN financial_reports.Fund_Amount_Table
pipelined parallel_enable IS
cur_row financial_reports.Fund_Amount_Record;
BEGIN
FOR cur_row IN
SELECT
to_number(substr(bu5.usrdata, 1, 1)) As SECTION_ID
,to_number(substr(bu5.usrdata, 2, 1)) As SUB_SECTION_ID
,to_number(substr(bu5.usrdata, 4, 2)) AS LINE_NUMBER
,to_number(substr(bu5.usrdata, 7, 2)) As FUND_ID
,sum(be.amt) AS AMOUNT
FROM
linc.budgetdb_usr5@stjohnsfp bu5
JOIN linc.budgetdb_event@stjohnsfp be ON
bu5.keyvalue = be.acctno
WHERE
bu5.keyvalue like '__-__-__-____-____-_____'
AND bu5.usrdata like '__-__-__'
AND bu5.fieldnum = 1
AND bu5.ispecname = 'GLMST'
AND to_number(substr(bu5.usrdata, 7, 2)) = 1
GROUP BY
bu5.usrdata
ORDER BY
bu5.usrdata
LOOP
PIPE ROW(cur_row);
END LOOP;
END Fund_Amount;
END financial_reports;
SQL that do not work …
CREATE OR REPLACE PACKAGE BODY financial_reports AS
FUNCTION Fund_Amount (Fund_Id IN NUMBER)
RETURN financial_reports.Fund_Amount_Table
pipelined parallel_enable IS
cur_row financial_reports.Fund_Amount_Record;
fund_id_int NUMBER;
BEGIN
fund_id_int := Fund_Id;
FOR cur_row IN
SELECT
to_number(substr(bu5.usrdata, 1, 1)) As SECTION_ID
,to_number(substr(bu5.usrdata, 2, 1)) As SUB_SECTION_ID
,to_number(substr(bu5.usrdata, 4, 2)) AS LINE_NUMBER
,to_number(substr(bu5.usrdata, 7, 2)) As FUND_ID
,sum(be.amt) AS AMOUNT
FROM
linc.budgetdb_usr5@stjohnsfp bu5
JOIN linc.budgetdb_event@stjohnsfp be ON
bu5.keyvalue = be.acctno
WHERE
bu5.keyvalue like '__-__-__-____-____-_____'
AND bu5.usrdata like '__-__-__'
AND bu5.fieldnum = 1
AND bu5.ispecname = 'GLMST'
AND to_number(substr(bu5.usrdata, 7, 2)) = fund_id_int
GROUP BY
bu5.usrdata
ORDER BY
bu5.usrdata
LOOP
PIPE ROW(cur_row);
END LOOP;
END Fund_Amount;
END financial_reports;
Error … (This works without the parameter)
Error starting at line 43 in command:
select * from table(financial_reports.Fund_Amount(1) )
Error at Command Line:1 Column:14
Error report:
SQL Error: ORA-22905: cannot access rows from a non-nested table item
Any help would be greatly appreciated

try renaming your parameter so as not to confuse with what you are using in your column " to_number(substr(bu5.usrdata, 7, 2)) AS FUND_ID":
CREATE OR REPLACE PACKAGE BODY financial_reports AS
  FUNCTION Fund_Amount (pFund_Id IN NUMBER)
    RETURN financial_reports.Fund_Amount_Table
    pipelined parallel_enable IS
    cur_row financial_reports.Fund_Amount_Record;
    fund_id_int NUMBER;
  BEGIN
    fund_id_int := pFund_Id;
    FOR cur_row IN ( SELECT to_number(substr(bu5.usrdata, 1, 1)) As SECTION_ID,
                            to_number(substr(bu5.usrdata, 2, 1)) As SUB_SECTION_ID,
                            to_number(substr(bu5.usrdata, 4, 2)) AS LINE_NUMBER,
                            to_number(substr(bu5.usrdata, 7, 2)) As FUND_ID,
                            sum(be.amt) AS AMOUNT
                       FROM linc.budgetdb_usr5@stjohnsfp bu5
                              JOIN linc.budgetdb_event@stjohnsfp be ON bu5.keyvalue = be.acctno
                      WHERE bu5.keyvalue like '__-__-__-____-____-_____'
                        AND bu5.usrdata like '__-__-__'
                        AND bu5.fieldnum = 1
                        AND bu5.ispecname = 'GLMST'
                        AND to_number(substr(bu5.usrdata, 7, 2)) = fund_id_int
                     GROUP BY bu5.usrdata
                     ORDER BY bu5.usrdata ) LOOP
      PIPE ROW(cur_row);
    END LOOP;
  END Fund_Amount;
END financial_reports;
