I am getting the error "System.InvalidOperationException: Only one instance of a ScriptManager can be added to the page." I know the error is because I have toolkitscriptmanager on the page, but i need it there. I don't know where the other declaration for a scriptmanager is??

<%@ Control Language="C#" AutoEventWireup="true" ClassName="uc_ORItem" CodeFile="uc_ORItem.ascx.cs"
    Inherits="uc_ORItem" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
<style type="text/css">
    td
    {
        font-family: Tahoma;
        font-size: 12px;
    }
    .textbox
    {
        font-family: Tahoma;
        font-size: 12px;
    }
</style>
<table cellpadding="0" cellspacing="0" border="0">
    <tr>
        <td valign="middle">
            <cc1:ToolkitScriptManager EnableScriptLocalization="true" ID="ToolkitScriptManager1" runat="server">

            function itemSelected(source, eventArgs)
            {
                //alert("key: " + eventArgs.get_text() + "  value: " + eventArgs.get_value());
