SQL QUERY

Hi, I am having trouble with the following piece of SQL.

I have 2 Tables: POHEAD and POLINE - THEY SHOULD BE LINKED ON THE ORD_NO field, primary for both.  I am trying to identify and return lines on a purchase order where the same catalogue item has been ordered twice.

I want to get the ORD_NO from the POHEAD Table, ORD_NO & ORD_LIN_NO & CATALOGUE fron the POLINE table, where the same catalogue item has been ordered twice on 1 ORD_NO for sysdate.

I have tried a few options below the latest, but this is giving me an error back

SELECT
RSSPOHEAD.ORD_NO,
RSSPOLINE.ORD_NO      
FROM
RSSPOHEAD,
RSSPOLINE
WHERE
RSSPOHEAD.ORD_NO=RSSPOLINE.ORD_NO
AND
RSSPOLINE.STATUS <> 'Z'
 AND
RSSPOHEAD.ORD_DATE = to_char(sysdate,'YYYYMMDD')
HAVING
      count(RSSPOLINE.CATALOGUE) <>count (distinct RSSPOLINE.CATALOGUE)

 AND RSSPOLINE.STATUS <> 'Z'
 AND RSSPOHEAD.ORD_DATE = to_char(sysdate,'YYYYMMDD')
 GROUP BY RSSPOHEAD.ORD_NO,RSSPOLINE.ORD_NO, RSSPOLINE.CATALOGUE
