Trigger Bad Bind Value Auto Increment

Question

I am new to the Oracle world and am trying to make the switch from MySQL so my apologies if this seems like a silly question.
I am trying to figure out what is wrong with my trigger code. Basically , I am trying to create an auto-increment solution using some example code I found on the Internet.
I have a fairly simple table structure:
CREATE TABLE "CIMS"."computerSoftware"
( "computerSoftware_id" NUMBER(11,0),
"cid" NUMBER(11,0) DEFAULT 0 NOT NULL ENABLE,
"publisher" VARCHAR2(100 CHAR) DEFAULT NULL,
"name" VARCHAR2(100 CHAR) DEFAULT NULL,
"version" VARCHAR2(100 CHAR) DEFAULT NULL,
"serialNumber" VARCHAR2(100 CHAR) DEFAULT NULL,
"unlimited" NUMBER(4,0) DEFAULT 0,
"copies" NUMBER(9,0) DEFAULT 1 NOT NULL ENABLE,
"master" NUMBER(4,0) DEFAULT 0,
PRIMARY KEY ("computerSoftware_id")
My Trigger looks like this:
CREATE OR REPLACE TRIGGER "CIMS"."TR_CompSoftware_ID"
BEFORE INSERT ON CIMS."computerSoftware"
REFERENCING OLD AS OLD NEW AS NEW
FOR EACH ROW
BEGIN
IF (:new.computerSoftware_id IS NULL) then
SELECT S_CompSoftware_ID.NEXTVAL
INTO :new.computerSoftware_id
FROM dual;
end IF;
END;
And finally, here is my sequence:
CREATE SEQUENCE "CIMS"."S_CompSoftware_ID" MINVALUE 1
MAXVALUE 999999999999999999999999999 INCREMENT BY 1 START WITH 1 CACHE 10 NOORDER NOCYCLE
When I try to save the trigger I receive the following error:
PLS-00049: bad bind variable 'NEW.COMPUTERSOFTWARE_ID'
Any help is much appreciated!

And, this is the way - you can rectify this problem ->
