I'm a newbie to Razor, so hopefully this is just a simple Razor rule i'm not aware of or something... So here goes:

I'm trying to create a navigation based on one i found on the forum previously

It works okay, but if i try to add my own conditionals (such as my logic for the home page), it breaks.  Every time.

Is there a rule for Razor that i'm missing regarding conditionals?  Does anybody have a good link for a general intro to Razor that is relevant to the Umbraco context?

My code:

@*
NESTED NAVIGATION WITH START AND FINISH LEVELS
=======================================
This snippet makes it easy to do navigation based lists! It'll automatically produce a nested list all children of a page within certain
levels in the hierarchy that's published and visible (it'll filter out any pages with a property named "umbracoNaviHide"
that's set to 'true'.
Based on the inbuilt Navigation script in Umbraco 4.7                                                      
 
How to Customize for re-use (only applies to Macros, not if you insert this snippet directly in a template):
- If you add a Macro Parameter with the alias of "StartLevel" you can define the starting level for which nodes will be displayed
- If you add a Macro Parameter with the alias of "FinishLevel" you can define the finish level for which nodes will be displayed

<div id="nav">
 
  @if (Parameter.AssignHomeManually == 1) {
    <ul id="topnav" class="sf-menu">
      <li><a href="/">HOME</a></li>
    </ul>
  }
 
  @nav(Model, Convert.ToInt32(Parameter.FinishLevel))
 
</div>
 
                                                    
@helper nav(dynamic node, int level) {
 
  var selected = Array.IndexOf(Model.Path.Split(','), node.Id.ToString()) >= 0 ? " class=\"current\"" : "";
 
  if(level > 0) {
    if(node.Children.Any()) {
      <ul id="topnav" class="sf-menu">
        @foreach(var child in node.Children.Where("Visible")) {
          <li>
            <[email protected](selected) href="@child.Url">@child.Name</a>
            @nav(child, level - 1)
          </li>
        }
      </ul>
    }
  }
}
 

Thanks heaps
