Javascript

Hello everyone,

Below is a Javascript i am using to display a Countdown client side.
It works fine. But I need to program the variable from the asp.net code behind in C#

<script language="JavaScript">
    TargetDate = "12/31/2020 5:00 AM";
    BackColor = "palegreen";
    ForeColor = "navy";
    CountActive = true;
    CountStepper = -1;
    LeadingZero = true;
    DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds.";
    FinishMessage = "It is finally here!";
</script>

Current I have a label which display the Target Date and that works but I need to get the TargetDate in the javascript to be = to the label.
Tried to fire the code from the code behind but no luck.

<asp:label id="lblDateTime" runat="server" text="" xmlns:asp="#unknown"></asp:label>

Any Ideas?? Please help

Thanks


UPDATE 1 by OP:
Sorry No Go.. Here is what I have tried so far

<script language="JavaScript">
      //TargetDate = "7/11/2010 5:00 PM";
      //..TargetDate = document.getElementById("<%=hdnStatus.ClientID%>").value;
      TargetDate = .getElementById("lblDateTime").innerText;
      BackColor = "palegreen";
      ForeColor = "navy";
      CountActive = true;
      CountStepper = -1;
      LeadingZero = true;
      DisplayFormat = "%%H%% Hours, %%M%% Minutes, %%S%% Seconds.";
      FinishMessage = "Download Starting";
</script>
Also
<script language="JavaScript">
      //TargetDate = "7/11/2010 5:00 PM";
      //TargetDate = document.getElementById("<%=hdnStatus.ClientID%>").value;
      getElementById("lblDateTime").innerText = TargetDate;
      BackColor = "palegreen";
      ForeColor = "navy";
      CountActive = true;
      CountStepper = -1;
      LeadingZero = true;
      DisplayFormat = "%%H%% Hours, %%M%% Minutes, %%S%% Seconds.";
      FinishMessage = "Download Starting";
</script>

The date dispaly fine in the label so where getting that much to happen
