I'd like to know how I can use a session variable inside the SelectCommand of an asp:AccessDataSource control.

ASP code: 

 

<asp:AccessDataSource ID="dSrcMarcacoes" runat="server"
                                DataFile="~/App_Data/Clinica.mdb"
                                

                                

                                SelectCommand="SELECT COLABORADORES.NOME_COLAB, MARCACOES.DATA, MARCACOES.HORA, MARCACOES.SALA FROM ((MARCACOES INNER JOIN COLABORADORES ON MARCACOES.ID_MEDICO = COLABORADORES.ID_COLABORADOR) INNER JOIN PACIENTES ON MARCACOES.ID_PACIENTE = PACIENTES.ID_PACIENTE) WHERE (MARCACOES.ID_PACIENTE = @SelectUser)">
                                <SelectParameters>
                                    <asp:SessionParameter Name="SelectUser" SessionField="Utilizador" />
                                </SelectParameters>
                            </asp:AccessDataSource>

  The above code does not work - I simply want the where clause to be defined by the Session Variable "Utilizador" - not using codebehind!
