Help from a datepicker master please! Trouble setting the date correctly.

Help from a datepicker master please! Trouble setting the date correctly.

Hi there, could really use some pointers from an experienced datepicker user.

I have a gridview in an ASP.net webform.  One column of the grid is composed of both an <asp:label/> and an <input type="hidden"/> control.

I have managed to get a datepicker to appear in every row of this column and for the date of each datepicker to be set by the value of the <input type:hidden> control (a list of dates). The label shows the same data as text. When I click on an icon in the row the datepicker appears showing the same date as the label text.  This is great.  The problem is when my firends run the exact same sourcecode with everything identical the datepickers are stuck showing only todays date in every datepicker!? All the id names and fields are the same - same datasource for the dates to be shown, everything is identical as far as I can see but the correct dates only appear on my laptop.

Here is the code for the datepicker:
  1.                       <script>
  2.                        
  3.                           $(function () {
  4.                           $(".picker").datepicker({
  5.                                   showOn: "button",
  6.                                   buttonImage: "/images/calendar2.png",
  7.                                   buttonImageOnly: true,
  8.                                   buttonText: "calender"
  9.                                   });
  10.                                   $(".picker").datepicker("setDate", $(".picker"))
  11.                                   });

  12.                       var prm = Sys.WebForms.PageRequestManager.getInstance();
  13.                       if (prm != null) {
  14.                           prm.add_endRequest(function (sender, e) {
  15.                                   if (sender._postBackSettings.panelsToUpdate != null) {
  16.                                       $(".picker").datepicker({
  17.                                           showOn: "button",
  18.                                           buttonImage: "/images/calendar2.png",
  19.                                           buttonImageOnly: true,
  20.                                           buttonText: "calender"
  21.                                       });
  22.                               }
  23.                               });
  24.                       };
  25.                       </script>

  26. And here is the code for the HTML column:

          <ItemTemplate>
          <asp:Label ID="lblDate" runat="server" 
Text='<%# Convert.ToDateTime(Eval("Date")).ToString("MM/dd/yyyy") %>' Height="15%">      </asp:Label>
          <input type="hidden" class="picker" id="datepicker" 
value='<%# Convert.ToDateTime(Eval("Date")).ToString("MM/dd/yyyy") %>'/>   
           </ItemTemplate>



Any help greatly appreciated - i'm pulling my hair out
