</td>
<td>

<td>
   <div class=checkboxes>
      <LABEL style="white-space: nowrap;">

      </LABEL><BR>                  
      <LABEL style="white-space: nowrap;">
      <INPUT type="checkbox" name="user_registered" class="checkbox2"  value="22"   >
   </div>
</td>

   <td> </td>

Answer 1

For each div, sum the values of the (checked?) checkboxes, then find the next TD (next sibling of parent TD) and use the total as the contents of the TD you've found.

$('div.checkboxes').each( function() {
   var total = 0;
   $(this).find('input:checkbox:checked').each( function() {
       total += parseInt( $(this).val() );
   });
   $(this).closest('td').next('td').html(total);
});

Answer 2

You can do it like this:

​$("div.checkboxes").each(function() {
    var total = 0;
    $(this).find(":checkbox").each(​​​​​​​​​​​​​​​​function() {
        total += parseInt(this.value, 10);
    });
    $(this).parent().next().text(total);
});

You can give it a try here, you'll want to change .find(":checkbox") to .find(":checkbox:checked") if you only want to sum the checked values.
