DatePicker double update not working ... (noob)

DatePicker double update not working ... (noob)

Hi,
 
Bit of a noob at this, fumbling along best as I can ...
 
This bit of code is working fine ...
 
  1. <script> 
     $(document).ready(function(){
      $(function() {
       $( "#datepicker" ).datepicker(); 
      });
      $( "#datepicker" ).change(function() {
       $( "#datepicker" ).datepicker("option", "dateFormat", "DD, d MM, yy");  
      });  
     });
    </script>








  2. ...
      <td class='xx_tdc'><input type='text' id='datepicker' size='30' /></td>

 
But when I try to add this in it only completes the first step (format the date)
 
  1. <script>
      $(document).ready(function(){
       $(function() {
        $( "#datepicker" ).datepicker();
       });
       $( "#datepicker" ).change(function() {
        $( "#datepicker" ).datepicker("option", "dateFormat", "DD, d MM, yy");
        $( "#fish" ).value("Date has been selected");
       });
      });
    </script>









  2. ...
      <td class='xx_tdl' colspan='3' id='fish'>No date selected yet</td>
      <td class='xx_tdc'><input type='text' id='datepicker' size='30' /></td>

 
Can anyone suggest how to update the text of a second <td> item, or even the value of a text input box item?
 
Cheers
Greg
