Select most recent post

Question

Hello everyone,
I have 2 tables:
- FORUM_MESSAGE
ID | ID_FORUM | ID_USER | TITLE | DATE
1 1 1 post 1 10/11/2005
2 2 2 post 2 09/10/2005
3 1 1 post 1 08/06/2005
- FORUM_USER
ID | ID_TYPE | NAME
1 1 admin
2 2 user
What i need to get is the most recent TITLE of each forum posted by an admin.
This is what i have done, but it is not working:
SELECT FORUM_MESSAGE.TITLE
FROM FORUM_MESSAGE, FORUM_USER
WHERE FORUM_MESSAGE.DATE = (SELECT MAX(FORUM_MESSAGE.DATE)
               FROM FORUM_MESSAGE GROUP BY FORUM_MESSAGE.ID_FORUM)
AND FORUM_MESSAGE.ID_USER = FORUM_USER.ID
AND FORUM_USER.ID_TYPE = 1
Could someone help me? i am lost...
Thanks in advance

but still does not compile If it does not compile there must be a compilation error. Please use cut'n'patse to snip your code and the results from SQL*Plus. Like this
SQL> CREATE TABLE forum_user (id number, type number, name varchar2(10))
  2  /
Table created.
SQL>
SQL> INSERT INTO forum_user VALUES (1, 1, 'admin')
  2  /
1 row created.
SQL> INSERT INTO forum_user VALUES (2, 2, 'APC')
  2  /
1 row created.
SQL>
SQL> CREATE TABLE forum_message (id number, forum_id number, user_id number , title varchar2(30), pd
