Procedure Based Forms( a little !)

Question

Freinds!
I have mada a form based on a package:
======================================
Create or Replace Package vchrpro AS
TYPE glrec is RECORD (company_code varchar2(4),
voucher_type varchar2(4),
voucher_seq varchar2(6),
user_code varchar2(8)
TYPE glcur is REF CURSOR RETURN glrec;
PROCEDURE glquery(resultset IN OUT glcur,
v_company_code in varchar2, v_voucher_type in varchar2);
END vchrpro;
show errors;
Create or Replace Package Body vchrpro AS
PROCEDURE glquery(resultset IN OUT glcur,
v_company_code in varchar2, v_voucher_type in varchar2) IS
BEGIN
OPEN resultset FOR
SELECT a.company_code, a.voucher_type, a.voucher_seq, a.user_code
FROM gl_voucher a,gl_voucher_type b
WHERE a.company_code=b.company_code and
a.voucher_type=b.voucher_type and
a.user_code=b.user_code and
a.company_code=v_company_code and
a.voucher_type=v_voucher_type
ORDER BY a.voucher_type;
CLOSE resultset;
END glquery;
END vchrpro;
show errors
========================================
the package is succesfully created and also
the form.But the prob. is that i am not sure
about the "Query Data Source Arguments" of
a form's block property. i.e what i will
give "Type Name" and "Value" to my procedure's parameter "resultset" (i have given nothing)AND when i run the form and
execute the query error says:
FRM-40505 Oracle error: unable to perform
query.
Kindly help me it is very important & urgent!
also let me know if i have conveyed properly.
Many thaks!

Take a look at
"Forms and Reports Feature/Benefit Demos"
that you can also get from: http://technet.oracle.com/sample_code/products/forms/content.html
There is a sample of a procedure based form there.
