I am having an issue with my Multinode tree picker Macro.  I have the MTP in a property that is in my Global doctype.  Some pages/nodes are using the MTP to put certain content on pages I need them for.  

My issue is, on the pages that I have picked something in the MTP, they work fine. But for pages that I have not chosen anything, I am getting "Error loading MacroEngine script (file: SurveyModule.cshtml)"

I have nod idea why, I have tried a few things.  I did a simple test to see if the my picker was Empty and print out some text and that seemed to work. 

BUT when I try to find my node properties, it gives me the MacroEngine error on the pages that done have anything selected in the MTP.  It almost seems to be when I add my var it errors. But I don't know for sure.  Can someone please help me out?

My code is below.

@{
   var nodeItem = @Model.surveyModulePicker;
    var surveyNode = @Model.NodeById(nodeItem.InnerText); 

  @*TODO: Put logic in to test if the current page has anything in the surveyModulePicker and now show it on those pages. Currently shows on all pages.*@
  if(@Model.GetProperty("surveyModulePicker") != string.Empty){
 
   if(@surveyNode.HasValue("surveyModuleURL")){
                                           
    <div class="surveyHintModule">
      <span class="surveyModuleCloseBtn">Close X</span>
