I have a website with different root paths , So for example Home Mechanical

These are both top level under Content.

I have a document type with a slider in it and some other properties. My issue is that everything works fine under home, but for what ever reason when on the home page (or others underneath) and browsing to Mechanical the document type that worked fine under root home all of the sudden starts having null reference exceptions on the items with in the Document.

I am not sure what I am missing - I am thinking something gets messed up with the path to the items.

Some basic code of the page with issues. Remember it works in the home folder path but when browsing to the Mechanical it does not work - I get the null reference exceptions , the rest of the page objects seem to work fine . Does any one have any idea what I am doing wrong here .Yes I want the structure ..

@{
    string carouselId = "myCarouselSlide";
    var carousel = Model.Value<IEnumerable<IPublishedElement>>(carouselId);
}

@if (carousel != null && carousel.Any())
{
    <div class="carousel slide" style="width:80%;margin: auto;" data-ride="carousel" id="@carouselId">
        <div class="carousel-inner" role="listbox">
            @{
                int slideCount = 0;
                foreach (var slide in carousel)
                {
                    string title = slide.Value<string>("slideTitle");
                    string subtitle = slide.HasValue("slideSubtitle") ? slide.Value<string>("slideSubtitle") : "";
                    string imageUrl = slide.Value<IPublishedContent>("slideImage")?.GetCropUrl(1024,433) ?? Href("~/img/logo.jpg");
                    IEnumerable<Link> links = slide.Value<IEnumerable<Link>>("slideLink");
                    Link link = links != null ? links.FirstOrDefault() : null;
