Multiple counts when joining files

[rob@xxxxxxxxx]

I can't seem to get this right:

SELECT DIOBLI, SUM(HQ.DIOBSZ) AS HQSIZE, 
               COUNT(HQ          ) AS HQNBROBJ, 
               SUM(HQ2.DIOBSZ) AS HQ2SIZE, 
               COUNT(HQ2          ) AS HQ2NBROBJ, 
               MAX(HQ.DICDAT) AS CHANGEDDATE 
FROM ROB/GDIHQOBJ HQ LEFT OUTER JOIN ROB/GDIHQ2OBJ HQ2
     USING (DIOBLI, DIOBNM, DIOBTP) 
WHERE DIOBLI<>' ' AND DIOBLI <>'QDOC' 
GROUP BY DIOBLI 
ORDER BY DIOBLI
