I am trying to use the following code to make the root of sub-menu items appear highlighted when the sub items are selected.

This works on all pages, even those without sub-pages except the home page.

What am I missing?

                            <!ENTITY hidden "umbracoNaviHide = 1">

      </ul>
    </xsl:if>
  </li>

Many thanks.
