Update Label - using UpdateProgress

Revision 1
Hello Everyone,
I been trying for hours to figure out how to change the label inside the updateprogress.
when the user click send email button , it go through loop to check if the user is inside this location and if its then add the user email to the email list.
i want everytime the count inide the loop increase the label display how many emails sent.

If email <> "" Then
                   dcount += 1
<pre> Session("dcount") = dcount
<pre>Dim counterStatus As Label = CType(UpdateProgress1.FindControl("lblCounterStatus"), Label)
counterStatus.Text= Session("dcount") = dcount

the label never shows while it's searching

and here is my aspx

<asp:UpdatePanel ID="UpdatePanel2" runat="server">

                   <ContentTemplate>
                   <asp:Label ID="lblEmailStatus" runat="server"></asp:Label> <br />
                    <asp:Button ID="btnSend" runat="server" Style="text-align: center" Text="Send"
                   Width="101px" />


                                             <asp:Label ID="lblStatus2" runat="server" Text=""></asp:Label>
                                             <br />
