Il record non esiste o è stato cancellato

[orcim]

Cosa sbaglio in questo code?:

Dim id, SQL, Rec
id = Request.Querystring("id")

SQL = "SELECT * FROM anagrafica WHERE ID = "&id
Set Rec = Server.CreateObject("ADODB.Recordset")
Set Rec = Cn.Execute(SQL)

if REC.eof then
response.write "non ci sono records"
else
eseguia ltra query SQL
Set Rec = Server.CreateObject("ADODB.Recordset")
Set Rec = Cn.Execute(SQL)
end if

restituisce:

Error Type:
ADODB.Field (0x80020009)
Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.
