I am using Umbraco v6.2. and Contour version 3.0.21

Trying to follow this thread, I created a macro, cut and paste the sample code into and trimmed it down to be even more basic. I changed the GUID to the GUID on the settings tab on my contour form.

But I get an error and it is not working

My code:

@inherits Umbraco.Web.Macros.PartialViewMacroPage
@using Umbraco.Forms.Mvc.DynamicObjects
@using Umbraco.Forms.Core
@using Umbraco.Forms.Core.Services
@using Umbraco.Forms.Data.Storage

@try {

    RecordStorage storage = new RecordStorage();
    Record record = storage.GetRecord(new Guid("e1978f08-6471-4b13-87f2-84e8242ef137"));
    var recordFields = record.RecordFields.OrderBy(r => r.Value.Field.PageIndex).ThenBy(r => r.Value.Field.FieldsetIndex).ThenBy(r => r.Value.Field.SortOrder);

    <ul>
    @foreach (var field in recordFields) {

        <li>
            <b>@field.Value.Field.Caption</b><p>@field.Value.ValuesAsString()</p>
        </li>
    }
    </ul>
}
catch (Exception e) {
   @:Error  @e.ToString() 
}

Error:

Error System.ArgumentNullException: Value cannot be null. Parameter name: source at System.Linq.Enumerable.OrderBy[TSource,TKey](IEnumerable`1 source, Func`2 keySelector) at ASP._Page_Views_MacroPartials_GetFormData_cshtml.Execute() in c:\dev\www\WHRX-dev\WHRX-working\WHRX\Views\MacroPartials\GetFormData.cshtml:line 44

Line 44 is: 

var recordFields = record.RecordFields.OrderBy(r => r.Value.Field.PageIndex).ThenBy(r => r.Value.Field.FieldsetIndex).ThenBy(r => r.Value.Field.SortOrder);

Any ideas?  I am really stuck

Thanks,

Karen
