      <label for="<?php echo $this->get_field_id('check_for_counter'); ?>">Check whether to display description or not</label> </p> 

      <p> <input type="radio" class="what_to_check_for" <?php checked($what_to_check_for ,'check_for_image'); ?> id="<?php echo $this->get_field_id('check_for_image'); ?>" value="check_for_image" name="<?php echo $this->get_field_name('what_to_check_for'); ?>" >
