Stored procedures

Hvad går der galt her? Jeg bruger stored procedures.. Det går galt når jeg bruger EXECUTE getNyheder, men det går fint hvis bare jeg bruger SELECT * FROM mintabel

<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SqlClient" %>

<script language="VB" runat="server">
Sub Page_Load(Sender As Object, E As EventArgs)
    Dim Conn As New SqlConnection(Session("dsn"))
    Dim Comm As New SqlCommand("EXECUTE getNyheder", Conn)   
    'Dim Comm As New SqlCommand("SELECT * FROM nyheder", Conn)
    Dim DR As SqlDataReader

    Comm.Connection.Open()
    DR    = Comm.ExecuteReader

    While DR.Read()
        Nyheder.Text    = DR.Item("tekst") & "<br>" & VBCrLf
    End while

    Comm.Connection.Close()
End sub
</script>

<asp:label id="Nyheder" runat="server"/>
