Hi all try as I might I can't get the following scenario to work..

What im trying to achieve is a loop through to the closes doctype which has a template and then a redirect..

I'm getting a syntax error stating { expected:

<%@ Master Language="C#" MasterPageFile="~/umbraco/masterpages/default.master" AutoEventWireup="true" %>

<asp:content ContentPlaceHolderId="ContentPlaceHolderDefault" runat="server">
<umbraco:Macro runat="server" language="cshtml">
@inherits umbraco.MacroEngines.DynamicNodeContext;

@{  
  if(Model.HasValue("umbracoRedirect"))
  {
    var nodeToRedirectTo = Library.NodeById(Model.umbracoRedirect);
    if(nodeToRedirectTo != null && nodeToRedirectTo.Visible) {
      Response.RedirectPermanent(nodeToRedirectTo.Url);
    }
  }
  
  var nodeForUrl = Model.Parent;
  while (nodeForUrl != null && !TemplateExists(nodeForUrl.Template))
  {
    nodeForUrl = nodeForUrl.Parent;
  }
  
  if(nodeForUrl.Visible) {
    Response.RedirectPermanent(nodeForUrl.Url);
  }
}

@functions {    
    public static bool TemplateExists(int templateId)
    {
      if (templateId <= 0) 
      {
        return false;
      }
      var template = new umbraco.cms.businesslogic.Template(templateId);
      return template.Alias == "BasePage" || (template.MasterTemplate != 0 && TemplateExists(template.MasterTemplate));
    }
}
</umbraco:Macro>
</asp:content>

This appears to save without errors:

@inherits umbraco.MacroEngines.DynamicNodeContext
@{  
  if(Model.HasValue("umbracoRedirect"))
  {
    var nodeToRedirectTo = Library.NodeById(Model.umbracoRedirect);
    if(nodeToRedirectTo != null && nodeToRedirectTo.Visible)
    {
      Response.RedirectPermanent(nodeToRedirectTo.Url);
    }
  }
  
  var nodeForUrl = Model.Parent;
  while (nodeForUrl != null  && !TemplateExists(nodeForUrl.Template))
  {
    nodeForUrl = nodeForUrl.Parent;
  }
  
  if(nodeForUrl.Visible)
  {
    Response.RedirectPermanent(nodeForUrl.Url);
  }
}

@functions {    
  public static bool TemplateExists(int templateId)
  {
    if (templateId <= 0) 
    {
      return false;
    }
    var template = new umbraco.cms.businesslogic.template.Template(templateId);
    return template.Alias == "BasePage" || (template.MasterTemplate != 0 && TemplateExists(template.MasterTemplate));
  }
}

I don't know where the error was exactly, but I did find that Template lives under the umbraco.cms.businesslogic.template namespace which is different from what you have.

Ah, okay, so the two changes I made to get the script to save without errors are:
1. Remove the semicolon after:
```
@inherits umbraco.MacroEngines.DynamicNodeContext
```
2. Include template in the path namespace for:
```
var template = newumbraco.cms.businesslogic.template.Template(templateId);
```
