Hi
I am developing a online store for one of our customers. I need a window with an iframe in the "my account" menu. This is what I have done so far: I created a model called CustomermisventasInfoModel and then I modified the Customer Controller.cs and the MyAccountNavigation.cshtml view to include my new model, then I created my view MisVentasInfo.cshtml and when I call "my account" page the following error occurs "A route named could not be found in the route collection. nopcommerce"

Can you please tell me what this error means? Can you help me?

Thanks in advance
