Problem With Custom Page Layout

Good morning, excuse me I have a question
-I want to create a custom page layout since I only want to place banners with links. My question is the following: I already created the personalized page with the banners, its name of "Dispatch=Custom"-"Pag.clima" the problem is that when I want to add in a menu link called "By climate" but when I put in the URL "Pag.clima" and I click it exits "page not found". Could you please tell me how I can call the custom page correctly so that I don't get that error?

Did you create the pag.php controller and clima.tpl template for the custom page?

Sorry I'm new to Cs-cart
-I don't believe pag.php controller and clima.tpl and the truth is I don't know how to do it, I would really appreciate if you could guide me with a simple example
