Related Links Razor Macro Umbraco 7

Questions

Does anyone have any related links razor working with a macro for Umbraco 7?

I unfortunately need to use the macro in the RTE and pass a parameter so can't use MVC, this just keeps throwing erros:

@inherits umbraco.MacroEngines.DynamicNodeContext
@using Newtonsoft.Json.Linq


@{
    var startNodeID = Parameter.ChooseButtonGroup;
}

@if (startNodeID != null)
{
    @* Get the start node as a dynamic node *@
	<h1>@startNodeID</h1>
    var startNode = Library.NodeById(startNodeID);
    
	foreach(var relatedLink in startNode.GetPropertyValue<JArray>("relatedLinks")) {
		
		<h1>@(relatedLink.Value<string>("title"))</h1>
		
	}
}


The error I'm getting is "'char' does not contain a definition for 'Value'"
