Hi

I am new to Umbraco and have a page Content structure like this:

Home
 - Models
   - - Model 1
   - - Model 2
   - - Model 3
About us
Contact Us

On the Home page I want to show the names and descriptions of Model 1, Model 2 and Model 3.  These three models have a document type of alias 'umbModelType'

(Note: I think it's the alias but the doc type labels it as 'Alternative link'  - why? :) )

After some searching I have tried the Razor script below but get this error:

'Error loading MacroEngine script (file: Homepage-modellist.cshtml)'

@inherits umbraco.MacroEngines.DynamicNodeContext

<ul>
@foreach (var item in @Model.AncestorOrSelf("umbModelType").Where("umbracoNaviHide != true"))   
{

<li>
       <h2><a href="@item.Url">@item.Name</a></h2>
       @item.modelDescription
  </li>
       
}

</ul>

I also tried this script from another source:

@inherits umbraco.MacroEngines.DynamicNodeContext

   // Get root node:
    var root = Model.AncestorOrSelf();

    // Get all descendants, filter by type:
    var nodes = root.Descendants("umbModelType");

    // Loop through the filtered nodes, displaying the properties:
    <ul>
    @foreach (var node in nodes)
    {
        <li>
            <h2>@node.Name</h2>
            @node.modelDescription
           
        </li>
    }
    </ul>

This script above threw this error when I saved it in Umbraco:

"error CS0103: The name 'nodes' does not exist in the current context"

Any help and pointers would be much appreciated.  Thanks in advance.
