I have this code, yet nothing is displaying, am I making a stupid mistake somewhere?  I just want to iterate through the entire site.

@inherits umbraco.MacroEngines.DynamicNodeContext
@{ 
  var homeNode = Model.AncestorOrSelf("HomePage");
  if (homeNode!= null) {
    <ul>
    @foreach (var item in homeNode.Children) {
      <li>
        <a href="@item.Url">@item.Name</a>
      </li>
      }
    </ul>
  }
}
