SQL Server creating tables

I am trying to create this tables in sql server 2008. I am able to create first two tables. But when I create 3rd table the employe table is removed. Here is the query.

CREATE DATABASE ABC_ORG

 USE ABC_ORG


CREATE TABLE EMPLOYEE
(
E_ID numeric(10) NOT NULL,
E_Name varchar(20) NOT NULL,
E_City varchar(10),
E_Designayion varchar(20) NOT NULL

CONSTRAINT PK_Emp PRIMARY KEY(E_ID)
)

CREATE TABLE SKILLS
(
  S_ID numeric(10) NOT NULL,
  S_Name varchar(20) NOT NULL,

  CONSTRAINT PK_SKILL PRIMARY KEY(S_ID)
)

CREATE TABLE EMP_SKILL
(
 E_ID NUMERIC(10) NOT NULL,
 S_ID NUMERIC(10),

 CONSTRAINT PK_EMP_SKILL PRIMARY KEY(E_ID, S_ID),

 CONSTRAINT EMP_SKILL FOREIGN KEY (E_ID) REFERENCES   EMPLOYEE(E_ID),

 CONSTRAINT SKILL_EMP_SKILL_FK FOREIGN KEY(S_ID) REFERENCES SKILLS(S_ID)
)
