Oracle Forms

Hello, I created a table and procedure for inserting large objects (images, documents..)into table and it works fine,
but now I want to create a form based on that procedure so that I can insert data with it.... but I am getting error FRM-10764,
I simplu do not understand how to add an argument of type TABLE or REFCURSOR to the procedure...below is the code for table and procedure :

CREATE TABLE MY_DOCS
(
DOC_ID NUMBER,
BFILE_LOC BFILE,
DOC_TITLE VARCHAR2(255 BYTE),
DOC_BLOB BLOB DEFAULT EMPTY_BLOB()
)




CREATE OR REPLACE PROCEDURE TESTFORMS.load (in_doc IN VARCHAR2, in_id IN NUMBER) IS

temp_blob BLOB := empty_blob();

bfile_loc BFILE;


BEGIN
bfile_loc := BFILENAME('DOC_DIR', in_doc);
INSERT INTO my_docs (doc_id, bfile_loc, doc_title) VALUES (in_id, bfile_loc, in_doc);
SELECT doc_blob INTO temp_blob FROM my_docs WHERE doc_id = in_id FOR UPDATE;
DBMS_LOB.OPEN(bfile_loc, DBMS_LOB.LOB_READONLY);
DBMS_LOB.OPEN(temp_blob, DBMS_LOB.LOB_READWRITE);
DBMS_LOB.LOADFROMFILE(temp_blob, bfile_loc, dbms_lob.getlength(bfile_loc));

DBMS_LOB.CLOSE(temp_blob);

DBMS_LOB.CLOSE(bfile_loc);

COMMIT;
END load;
/
