Newbie, need help creating tables in sql2008R2

Hi everyone,

I am new to SQL and I am trying to learn my way around it on my own time.

I am using SQL2008R2 and trying to create tables following the instructions on the 'Microsoft SQL Server 2008, Steb by Step' by Mike Hotek.

Following the examples, I am trying to execute the following query:

CREATE SCHEMA HumanResources AUTHORIZATION dbo
GO

CREATE TABLE Customers.Customer
(CustomerID     INT         IDENTITY(1,1),
CompanyName     VARCHAR(50) NULL,
FirsName        VARCHAR(50) NULL,
LastName        VARCHAR(50) NULL,
ModifiedDate    DATE        NOT NULL)
GO

But, every time I try to execute this query I get the following error mesage:

Msg 2760, Level 16, State 1, Line 1
The specified schema name "Customers" either does not exist or you do not have permission to use it.

I have tried to use different names for the table, regardless the name I try to assign I still get teh same problem.

I have tried creating new database and create tables with different names under the 'test database' but I always get the same error when i try to use the Table_x.TestTable (table name DOT table name) notation.

I believe I have the right premisions as I am logged-in as Administrator on the system and my 'Administrator' account appears under Databases->Security->Logins.

Any help would be much appreciated.

Regads,
