PL/SQL: Executing a procedure from within another procedure

Question

Hello, I'm a newbie and I need help on how to execute procedures from within another procedure. The procedure that I call from within the procedure have return values that I want to check.
I tried: EXECUTE(user_get_forum_info(p_forumid, var_forum_exists, var_forum_access, var_forumname));
but I get the error message:
PLS-00103: Encountered the symbol "USER_GET_FORUM_INFO" when expecting one of the following::= . ( @ % ; immediate
The symbol ":=" was substituted for "USER_GET_FORUM_INFO" to continue.
And when I tried: EXECUTE(user_get_forum_info(p_forumid, var_forum_exists, var_forum_access, var_forumname));
I get the error message:
PLS-00222: no function with name 'USER_GET_FORUM_INFO' exists in this scope
PL/SQL: Statement ignored
The procedure USER_GET_FORUM_INFO exists. (don't understand why it says "no FUNCTION with name", it's a procedure I'm executing)
I'm stuck so thanks for any help...
Below is all the code. I'm using Oracle 9i on RedHat Linux 7.3.
================================================================================
CREATE OR REPLACE PROCEDURE user_forum_requestsaccess (
p_forumid IN NUMBER,
p_requestmessage IN VARCHAR2
AS
var_forumid NUMBER;
var_forum_exists NUMBER;
var_forum_access NUMBER;
request_exists NUMBER;
var_forumname VARCHAR2(30);
FORUM_DOESNT_EXIST EXCEPTION;
FORUM_USER_HAS_ACCESS EXCEPTION;
FORUM_REQUEST_EXIST EXCEPTION;
BEGIN
SELECT SIGN(NVL((SELECT request_id FROM forum.vw_all_forum_requests WHERE forum_id = p_forumid AND db_user = user),0)) INTO request_exists FROM DUAL;
EXECUTE(user_get_forum_info(p_forumid, var_forum_exists, var_forum_access, var_forumname));
IF var_forum_exists = 0 THEN
RAISE FORUM_DOESNT_EXIST;
ELSIF var_forum_access = 1 THEN
RAISE FORUM_USER_HAS_ACCESS;
ELSIF request_exists = 1 THEN
RAISE FORUM_REQUEST_EXIST;
ELSE
INSERT INTO tbl_forum_requests VALUES (SEQ_TBL_FORUM_REQ_REQ_ID.NEXTVAL, SYSDATE, p_requestmessage, p_forumid, user);
INSERT INTO tbl_forum_eventlog VALUES (SEQ_TBL_FORUM_EVNTLOG_EVNT_ID.NEXTVAL,SYSDATE,1,'User ' || user || ' requested access to forum ' || var_forumname || '.', p_forumid,user);
COMMIT;
END IF;
EXCEPTION
WHEN
FORUM_DOESNT_EXIST
THEN RAISE_APPLICATION_ERROR(-20003,'Forum doesnt exist.');
WHEN
FORUM_USER_HAS_ACCESS
THEN RAISE_APPLICATION_ERROR(-20004,'User already have access to this forum.');
WHEN
FORUM_REQUEST_EXIST
THEN RAISE_APPLICATION_ERROR(-20005,'A request to this forum already exist.');
END;
GRANT EXECUTE ON user_forum_requestsaccess TO forum_user;

you don't have to use execute when you want to execute a procedure (only on sql*plus, you would use it)
just give the name of the funtion
create or replace procedure test
as
begin
    dbms_output.put_line('this is the procedure test');
end test;
create or replace procedure call_test
as
begin
    dbms_output.put_line('this is the procedure call_test going to execute the procedure test');
    test;
end call_test;
begin
    dbms_output.put_line('this is an anonymous block calling the procedure call_test');
    call_test;
end;
