when i copied my aspx code with Jquery having no Masterpage in a new aspx page jquery stopped working

when i copied my aspx code with Jquery having no Masterpage in a new aspx page jquery stopped working

though i have clearly add reference of my jquery file and ajax link

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
  <link  rel="Stylesheet" type="text/css" href="Css/Master.css" />
   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js" type="text/javascript"></script>
   <script  src="JS/jquery-1.6.2.min.js" type="text/javascript"></script>
     <script language="javascript"  type="text/javascript">

when a User clicks on a link it's onclick event fired and its --"ID" is passed to the function Reset(tabId)
I have debugged it control moves properly
below tabId contains onclicked link ID then according to it appropriate link became visible
though in earlier page without MAsterpage it is working fine
$(tabId).show();

function Reset(tabId) {
             //debugger;
             $("#Dynamic_1").hide();
             $("#Dynamic_2").hide();
             $("#Dynamic_3").hide();
             $("#Dynamic_4").hide();
             $("#Dynamic_5").hide();
             $("#Dynamic_6").hide();

             tabId = "#" + tabId;
             $(tabId).show();

             $(tabId).css("background-color", "#fafafa");
             $(tabId).css("font-weight", "Bold");
         }

         $(document).ready(function() {
             Reset("Dynamic_1");

         });
    </script>
</asp:Content>
