Extremely urgent-file download issue

Question

My problem is I hava tabular form with ATTACHMENTS(Select List), ID, Report_Name(linked to download the file). Report_Name has attribute to direct to the URL #OWNER#.download_my_file?p_file=#ID#&p_id=#ATTACHMENTS#
ATTACHMENTS returns (1,2,3,4,5,6) respectively. Even If select a report_type and click the report name, the URL that I receive has a null value for p_id. Any ideas why this is happening? Once I click the link I get URL not found because my URL only has <b>download_my_file?p_file=2399328756440204&p_id=</b>.It doesn't have the value for p_id. If I substitute manual values <b>download_my_file?p_file=2399328756440204&p_id=1</b> it is working fine.Any help will be extrememly helpful.
Here is my download_my_file proc code
create or replace PROCEDURE "DOWNLOAD_MY_FILE" (p_file in number,p_id in number) AS
v_id NUMBER:=p_id;
v_mime VARCHAR2(48);
v_length NUMBER;
v_file_name VARCHAR2(2000);
Lob_loc BLOB;
BEGIN
IF v_id = 1 THEN
SELECT MIME_TYPE, BLOB_CONTENT, name,DBMS_LOB.GETLENGTH(blob_content)
INTO v_mime,lob_loc,v_file_name,v_length
FROM file_subjects
WHERE id = p_file;
END IF;
IF v_id = 2 THEN
SELECT MIME_TYPE, SUMMARY_FILE_CONTENT, SUMMARY_NAME,DBMS_LOB.GETLENGTH(SUMMARY_FILE_CONTENT)
INTO v_mime,lob_loc,v_file_name,v_length
FROM file_subjects
WHERE id = p_file;
END IF;
IF v_id = 3 THEN
SELECT MIME_TYPE, SCREENER_FILE_CONTENT, SCREENER_NAME,DBMS_LOB.GETLENGTH(SCREENER_FILE_CONTENT)
INTO v_mime,lob_loc,v_file_name,v_length
FROM file_subjects
WHERE id = p_file;
END IF;
IF v_id = 4 THEN
SELECT MIME_TYPE, DISCUSSION_GUIDE_FILE_CONTENT, DISCUSSION_GUIDE_NAME,DBMS_LOB.GETLENGTH(DISCUSSION_GUIDE_FILE_CONTENT)
INTO v_mime,lob_loc,v_file_name,v_length
FROM file_subjects
WHERE id = p_file;
END IF;
IF v_id = 5 THEN
SELECT MIME_TYPE, BRIEFING_DOCUMENT_FILE_CONTENT, BRIEFING_DOCUMENT_NAME,DBMS_LOB.GETLENGTH(BRIEFING_DOCUMENT_FILE_CONTENT)
INTO v_mime,lob_loc,v_file_name,v_length
FROM file_subjects
WHERE id = p_file;
END IF;
IF v_id = 6 THEN
SELECT MIME_TYPE, MR_PLAN_FILE_CONTENT, MR_PLAN_NAME,DBMS_LOB.GETLENGTH(MR_PLAN_FILE_CONTENT)
INTO v_mime,lob_loc,v_file_name,v_length
FROM file_subjects
WHERE id = p_file;
END IF;
/*IF v_file_name is null THEN
SELECT MIME_TYPE, BLOB_CONTENT, name,DBMS_LOB.GETLENGTH(blob_content)
INTO v_mime,lob_loc,v_file_name,v_length
FROM file_subjects
WHERE id = p_file;
END IF;*/
-- set up HTTP header
-- use an NVL around the mime type and
-- if it is a null set it to application/octect
-- application/octect may launch a download window from windows
owa_util.mime_header( nvl(v_mime,'application/octet'),FALSE );
-- set the size so the browser knows how much to download
htp.p('Content-length: ' || v_length);
-- the filename will be used by the browser if the users does asave as
htp.p('Content-Disposition: attachment; filename="'||substr(v_file_name,instr(v_file_name,'/')+1)|| '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
end download_my_file;
