Object Expected Error in jQuery

Object Expected Error in jQuery

 I am using jQuery for reordering raws in a repeater control. Given below is the beginning of code snippet in jQuery.

<script language="javascript" type="text/javascript">

        setupOrderableTable();
        function setupOrderableTable() {
            debugger;
            var hdnDocumentIdsInOrder = document.getElementById('<%= hdnDocumentIdsInOrder.ClientID %>');
            var rowToInsert = null;
            var highlightLength = 500;
            var highlightColor = "#999999";
            var rowColor = "#F7FBFF";
            var alternatingColor = "#E7EFF7";
            var rowIndex = 0;








            $(".orderable tr").each(function () {
                $(this).css("background-color", (rowIndex++ % 2 == 0 ? rowColor : alternatingColor));

                // handle the move above click
                $("button:eq(1)", $(this)).click(function () {
                    $(rowToInsert).insertBefore($(this).parent().parent());
                });


...

...

...

 

</script>

 

 

And this is the repeater control

<table id="tblOrder" border="0" cellspacing="0" width="100%">
                    <colgroup>
                        <col style="width: 20px;" />
                        <col style="width: 350px;"/>
                        <col style="text-align: right;" />
                    </colgroup>
                    <asp:Repeater ID="Repeater" runat="server" >
                        <ItemTemplate><tr id= '<%# DataBinder.Eval( Container.DataItem, "ID") %>'><td><button>Move</button></td><td><img alt="" src='<%# DataBinder.Eval( Container.DataItem, "ImageUrl") %>' /><%# DataBinder.Eval( Container.DataItem, "Name") %></td><td><button>Move Above</button><button>Move Below</button></td></tr></ItemTemplate>
                    </asp:Repeater>
                </table>








 both are in a user control. I am accessing this user control from another aspx page where in the head section have these bindings

<script language="javascript" type="text/javascript" src="/Scripts/jquery/jquery-1.3.2.min.js" ></script>
<script language="javascript" type="text/javascript" src="/Scripts/jquery/jquery-ui-1.7.1.custom.min.js" ></script>
<script language="javascript" type="text/javascript" src="/Scripts/jquery/jquery-ui-personalized-1.6rc6.min.js" ></script>

 

Can anyone explain me what is the problem here? Thanks a tonne in advance.
