I am currently wanting to us the carousel from Cultiv Example project and i am getting the error

Error loading Razor Script ~/macroscripts/homecarousel.cshtml
'umbraco.MacroEngines.DynamicXml' does not contain a definition for 'url'

I have reviewed the razor forum and have tried most of the reccomendations with no luck.

<section id="gallery">
    <div class="pics">
        @if (Model.HasValue("carouselImages")) {
            dynamic mediaItems = Model.CarouselImages.mediaItem;
            if (mediaItems.Count() != 0)
            {
                foreach (var item in mediaItems)
                {
                    var image = item.Image;                
                    @*
                        If the type of the mediacropper is not XML (but a string) then there
                        are no crops defined, so I should not try to find the crops.
                    *@
                    var crops = image.crops;
                    if (crops.GetType().ToString() != "System.String")
                    {
                        <img src="@crops.Find("@name", "Homepage").url" alt="@image.nodeName" width="@image.umbracoWidth" height="@image.umbracoHeight"/><br />
                    }
                }
            }
        }        
    </div>
    <a href="#" id="prev"></a>
    <a href="#" id="next"></a>
</section>
