Good Morning Gentlemen,

Been scratching my head at this one for a few days, basically I'm trying to develop a macro to display page properties in groups of two. Usually I'd use .InGroupsOf(2) but my macro won't compile and has the error of:

 'umbraco.NodeFactory.Nodes' does not contain a definition for 'InGroupsOf' and no extension method 'InGroupsOf' accepting a first argument of type 'umbraco.NodeFactory.Nodes' could be found (are you missing a using directive or an assembly reference?)

Code below:

@using umbraco.NodeFactory
@using System.Linq
@{
        var specificNode = new Node(2654);
        var i = 0;
  }
@if (specificNode.Children.Count > 0)
{
 <div id="carousel-example-generic" class="carousel slide" data-ride="carousel" data-interval="false" style="clear: both">
  <!-- Indicators -->
  <ol class="carousel-indicators">
   @foreach (Node childPage in specificNode.Children.InGroupsOf(2))
   {
    if (i == 0)
    {
      <li data-target="#carousel-example-generic" data-slide-to="@i" class="active"></li>
    }
    else
    {
      <li data-target="#carousel-example-generic" data-slide-to="@i"></li>
    }
    i++;  
   }
  </ol>
   <!-- Wrapper for slides -->
   <div class="carousel-inner">
   @{i = 0;}
   @foreach (Node childPage in specificNode.Children)
   {
    if (i == 0)
    {
      <div class="item active">
      <div style="background: url('media/23917/purplebg.png') top left no-repeat; height: 200px; position: relative;">
      <div style="background-color: #FFFFFF; height: 157px; width: 34%; position: relative;top: 16px;right: -19px; border-radius: 15px;">
     </div>
           <p>@childPage.GetProperty("author").Value.ToString()</p>
     </div>
      <div id="testimonial" class="carousel-caption">
        @Html.Raw(childPage.GetProperty("testimonial").Value.ToString())
      </div>
    </div>
    }
    else
    {
      <div class="item">
      <div style="background: url('media/23917/purplebg.png') top left no-repeat; height: 200px;"><div style="background-color: #FFFFFF; height: 157px; width: 937px; position: relative;top: 16px;right: -19px; border-radius: 15px; width: 34%; height: 74%;">
     </div>
           @Html.Raw(childPage.GetProperty("author").Value.ToString())
     </div>
      <div id="testimonial" class="carousel-caption">
        @Html.Raw(childPage.GetProperty("testimonial").Value.ToString())
      </div>
    </div>
     
    }
    i++;
  }
  </div>
  <!-- Controls -->
  <a class="left carousel-control" href="#carousel-example-generic" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left"></span>
  </a>
  <a class="right carousel-control" href="#carousel-example-generic" data-slide="next">
    <span class="glyphicon glyphicon-chevron-right"></span>
  </a>
</div>
}

Edit: Unsure why half my code displays as commented out :S

Thanks,

Sam
