Thanks for the link but I still need some more help.
I added that project in my Plugins and do I have to do anything else? I am not able to see this plugin in admin -> Configuration -> plugins
I added following line in \Presentation\Nop.Web\Views\Catalog\ProductTemplate.SingleVariant.cshtml @Html.Action("Index", "Tracking", new { productId = Model.Id })
I am getting this exception: Execution of the child request failed. Please examine the InnerException for more information. InnerException: {"The controller for path '/p/5/1-oz-krugerrand' was not found or does not implement IController."}
