global $options;
?>
<form action="options.php" method="post">
  <?php $settings = get_option('options');
  ?>
  <?php settings_fields('theme_options'); ?>
    <fieldset>
        <legend>Counter Position:</legend>
        </br>
        <p>
            Right <input type="radio" name="position" value="right"/>
        <p>
            Left <input type="radio" name="position" value="left"/>
        <p>
            Center <input type="radio" name="position" value="center"/>
    </fieldset>
</form>

<?php


function r_set()
{
  register_setting('theme_options', 'options', 'validate_options');
}

add_action('admin_init', 'r_set');
function validate_options($value)
{
  global $sa_options;
  $val['position'] = $value['position'];
  return $val;
}
