MVC - Fix Error - Object doesn't support property or method 'valid'

 Watch this example on YouTube

 

To fix it replace in Layout

     @Scripts.Render("~/bundles/jquery")
    @Scripts.Render("~/bundles/jqueryui")
    @Scripts.Render("~/bundles/bootstrap")
    @RenderSection("scripts", required: false)
</body>
</html>

with

    @Scripts.Render("~/bundles/jquery")
    @Scripts.Render("~/bundles/jqueryui")
    @Scripts.Render("~/bundles/jqueryval")
    @Scripts.Render("~/bundles/bootstrap")
    @RenderSection("scripts", required: false)
</body>
</html>
