TRIGGER ERROR: bad bind variable

Question

Hello,
I'm just starting off with oracle and am trying to do the same as auto_increment in mysql is doing by creating this sequence and trigger, but on the trigger I am getting the following error:
error:
PLS-00049: bad bind variable 'TAKEOVER_USERS.TAKEOVER_UID'This is the code for trigger, table and sequence:
trigger:
CREATE OR REPLACE TRIGGER  "TAKEOVER_USERS_T1"
BEFORE
insert on "TAKEOVER_USERS"
for each row
begin
select TAKEOVER_UID.nextval into :takeover_users.TAKEOVER_UID from dual;
end;Table:
CREATE TABLE  "TAKEOVER_USERS"
   ( "TAKEOVER_UID" NUMBER NOT NULL ENABLE,
"TAKEOVER_FBID" VARCHAR2(20) NOT NULL ENABLE,
"takeover_accepted_terms" NUMBER(1,1) NOT NULL ENABLE,
"takeover_lastName" VARCHAR2(30),
"takeover_firstName" VARCHAR2(30),
"takeover_country" VARCHAR2(40),
"takeover_session" VARCHAR2(50) NOT NULL ENABLE,
"takeover_created" TIMESTAMP (6) NOT NULL ENABLE,
  CONSTRAINT "takeover_users_PK" PRIMARY KEY ("TAKEOVER_UID") ENABLE
   )sequence:
CREATE SEQUENCE   "TAKEOVER_UID"  MINVALUE 1 MAXVALUE 99999999999999 INCREMENT BY 1 START WITH 1 NOCACHE  NOORDER  NOCYCLEYou got any idea what I need to change to make this work?
Thanks!

if your DB is 11g you can try this
CREATE OR REPLACE TRIGGER  "TAKEOVER_USERS_T1"
BEFORE
insert on "TAKEOVER_USERS"
for each row
begin
:NEW.TAKEOVER_UID:=TAKEOVER_UID.nextval;
end;if 10g or older..
CREATE OR REPLACE TRIGGER  "TAKEOVER_USERS_T1"
BEFORE
insert on "TAKEOVER_USERS"
for each ROW
BEGIN
SELECT TAKEOVER_UID.NEXTVAL INTO :NEW.TAKEOVER_UID FROM dual;
end;Regards,
