Help!! Create Table From Variable !!!

I am passing a variable to a stored procedure using
db.ExecuteNonQuery("dbo.CreateTable", @symbol); < C# CODE >
the variable shows up fine but the stored procedure does not create the table...
I have tried everything... here are two versions of code that do not work...

using Dynamic Sql....

CREATE PROCEDURE dbo.CreateTable
@symbol nvarchar(10)
AS
DECLARE @Sql varchar
SELECT @SQL = 'Create Table [dbo].['+ @symbol +'](Symbol float'
SELECT @SQL = @SQL + '
, [Date] datetime
, [Open] float
, High float
, [Low] float
, [Close] float
, Volume integer)'
EXEC (@SQL)

this does nothing

And this one...(the longer version)

CREATE PROCEDURE dbo.CreateTable
(
@Symbol as varchar (10)
)
AS
DECLARE @SQL varchar(2000)
SET @SQL = "if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[@Symbol]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[@Symbol]
CREATE TABLE [dbo].[" + @Symbol + "] (
[Ticker] [varchar](10) Null,
[Date] [date] Null,
[Open] [float] NULL ,
[High] [float] NULL ,
[Low] [float] NOT NULL ,
[Close] [float] NULL ,
[Volume] [float] NULL ,
) ON [PRIMARY]"
EXEC(@SQL)

GIVES ME A 'The identifier that starts with... is too long, maximum length is 128'
