hello

I have following code in razor...

@using umbraco.BusinessLogic;
@using umbraco.MacroEngines;
@inherits umbraco.MacroEngines.DynamicNode
@inherits umbraco.MacroEngines.DynamicNodeContext
@{
  
  <div class="float:left;">
  
 
  @foreach(var item in Model.Parent.Children)
  {
    <a href="@item.Url">@item.Name</a><br />
  }
  </div>
  
  var nodes=@Model.Children;
   
   foreach(var node in nodes)
   {
     dynamic link = Library.MediaById(node.competitionThumbImage); 
     if(@node.GetProperty("isFirst").Value.ToString() != null && @node.GetProperty("isFirst").Value.ToString() == "True")
     {
     <a href="@node.NiceUrl" target="_blank"><img src="@link.umbracoFile" alt="@node.PageHeading" title="@node.PageHeading" width="126" height="126"/></a><br />
     <p>1st Rank</p>
     }
     else
     {
      <a href="@node.NiceUrl" target="_blank"><img src="@link.umbracoFile" alt="@node.PageHeading" title="@node.PageHeading" width="126" height="126"/></a><br />
     }
   }
  
}

Which checks True/false type property 'isFirst' and if it is checked then shows '1st rank' text. But it is not showing even when it is checked. So what is wrong in this? also, no error is coming.
