Error When Importing Data From Excel File

Hi!

This is what i'm doing:

IF EXISTS (SELECT srvname FROM master.dbo.sysservers srv WHERE srv.srvid !=

0 AND srv.srvname = N'ExcelSource')

EXEC master.dbo.sp_dropserver @server=N'ExcelSource', @droplogins='droplogins';

-
EXEC master.dbo.sp_addlinkedserver
@server = 'ExcelSource',
@srvproduct = 'Excel',
@provider = 'Microsoft.Jet.OLEDB.4.0',
@datasrc = @Chemin,
@provstr = 'Excel 8.0';


EXEC master.dbo.sp_addlinkedsrvlogin
@rmtsrvname = 'ExcelSource',
@useself = false,
@locallogin = NULL,
@rmtuser ='ADMIN',
@rmtpassword = NULL;

set @NomServ = 'ExcelSource';

This create a linkedServer to read my ExcelFile.

Then i'm doing this:

EXEC ('Insert into Elements (No_element, Nom_elem, Desc_elem, Code_grpe_classe, Tps_elem, Code_sgrpe, Code_produit)
Select No_element, Nom_elem, Desc_elem, Code_grpe_classe, Tps_elem, Code_sgrpe, Code_produit
from ' + @NomServ + '...[Elements$];')

This is where i got an error. The error is:
The OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "ExcelSource" does not contain the table "Elements$". The table either does not exist or the current user does not have permissions on that table.

I can't figure out what i'm missing. I've add permissions for EVERYONE on the file and on the folder just to be sure and i still have the same error. How can i check if the table [Elements$] exist ?
