Oracle create table not working when executed from SQL Script

I have a create table statement on a Oracle Script file and when I executed the script file, I am unable to create the table.

Content of script file

-- Table Creation Script

CREATE TABLE SampleTable
(

FIELD1 NUMBER NOT NULL,
FIELD2 DATE NULL,
FIELD3 DATE DEFAULT SYS开发者_开发技巧DATE,
FIELD4 DATE NULL,
FIELD5 NUMBER(10) DEFAULT 1,
FIELD5 NUMBER(10) NULL,
FIELD6 VARCHAR2(1000) NULL
);

I am getting a SP2-0734: error. Any ideas?

Two things:

One - remove that carriage return between ( and FIELD1

Two - there are two FIELD5 entries, giving the result ORA-00957: duplicate column name

Here:

CREATE TABLE SampleTable
(
FIELD1 NUMBER NOT NULL,
FIELD2 DATE NULL,
FIELD3 DATE DEFAULT SYSDATE,
FIELD4 DATE NULL,
FIELD5 NUMBER(10) DEFAULT 1,
FIELD6 NUMBER(10) NULL,
FIELD7 VARCHAR2(1000) NULL
);
