weight.js mistake

Thank you for this module!
I have tried module, and my experience was that the line 18 in weight.js is wrong.

Original version:

    $('fieldset#edit-weight', context).drupalSetSummary(function(context) {
      return Drupal.t('Weight: !weight', {'!weight' : $('#edit-weight--2 option:selected').val()});
    });

I think, this is the right solution:

    $('fieldset#edit-weight', context).drupalSetSummary(function(context) {
      return Drupal.t('Weight: !weight', {'!weight' : $('#edit-weight-weight option:selected').val()});
    });
