    Hey Everyone. I made the same mistake, see we followed the directions but some of the steps are easy to misinterpret if you are newer to Umbraco like myself.

    This issue occurs because we did not name the Property that we added to the page "slider".

    In the uSkySlider.cshtml (partial view) the line below show's the property it attempts to load.

    dynamic slider = @Model.Content.GetPropertyValue("slider");

    When I added the property to my home page I called it "Image Slider", so I changed that line in the cshtml to:

    dynamic slider = @Model.Content.GetPropertyValue("imageSlider");

    Hope this helps.
