Error when trying to use SUM with COUNT

Question

I have the following query which works fine. However, I need to add another column that is the SUM of the firs column ("OPEN"). I have also included that query but I cannot get it to work. Any help would be appreciated.
SELECT
TO_CHAR(TRUNC(R.RAD_SUBMIT_DATE, 'MM'), 'yyyy-mm') as THISDATE,
COUNT(decode(A.STATE_DESC, 'Approved', A.STATE_DESC)) +
COUNT(decode(A.STATE_DESC, 'Concept', A.STATE_DESC)) +
COUNT(decode(A.STATE_DESC, 'New', A.STATE_DESC)) +
COUNT(decode(A.STATE_DESC, 'Pending', A.STATE_DESC))
) as OPEN,
COUNT(decode(A.STATE_DESC, 'Approved', A.STATE_DESC)) +
COUNT(decode(A.STATE_DESC, 'Concept', A.STATE_DESC)) +
COUNT(decode(A.STATE_DESC, 'New', A.STATE_DESC)) +
COUNT(decode(A.STATE_DESC, 'Pending', A.STATE_DESC)) +
COUNT(decode(A.STATE_DESC, 'Completed', A.STATE_DESC)) +
COUNT(decode(A.STATE_DESC, 'Rejected', A.STATE_DESC)) +
COUNT(decode(A.STATE_DESC, 'Rescinded', A.STATE_DESC))
) as TOTAL
FROM RAW_APP_DATA R, APP_STATE A
WHERE R.RAD_STATUS = A.STATE_ID
AND (R.RAD_SUBMIT_DATE BETWEEN '01-AUG-02' AND '31-JAN-04')
GROUP BY TO_CHAR(TRUNC(R.RAD_SUBMIT_DATE, 'MM'), 'yyyy-mm')
ORDER BY TO_CHAR(TRUNC(R.RAD_SUBMIT_DATE, 'MM'), 'yyyy-mm')

You are right those are group functions not aggregate. However, if I try to group by with the group functions I get an error (see code).

ORA-00934: group function is not allowed here
Do I group by the columns individually?
