Hi there! I'm trying to code my sidebar.php but it breaks and goes all the way down below the posts

PHP:

<!-- begin sidebar -->
<div id="menu">
<?php  /* Widgetized sidebar, if you have the plugin installed. */
  if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar() ) : ?>

    <label for="s">SEARCH</label>
    <form id="searchform" method="get" action="#">
      <div>
        <input type="text" name="s" id="s" size="15" />
        <br />
        <input type="submit" value="TYPE HERE_" />
      </div>
    </form>
  <div class="bg-sidebar">
    <h2>MOST READ</h2>
    <ul>
      <li><a href="javascript:void(0);">Worth A Thousand Words</a></li>
      <li><a href="javascript:void(0);">Feed Your Head</a></li>
      <li><a href="javascript:void(0);">Aliquam tempus, eros commodo porta pretium</a></li>
      <li><a href="javascript:void(0);">Pellentesque quis libero dui</a></li>
      <li><a href="javascript:void(0);">Lorem ipsum dolor sit amet</a></li>
    </ul>

        <?php wp_get_archives('type=monthly'); ?>
      </li>
    </ul>
    <h2>LINKS</h2>

    </ul>
  </div>
  <?php endif; ?>
</div>
