How do I get my custom story to show up?

[A12]

Hello. I'm newer to Amnesia and decided to look into the custom level system.

The problem is, nomatter what I do, I can't get my level to show up. I got Amnesia: The Dark Descent from Steam, and have a custom folder in the custom stories one, inside said folder is another subfolder, maps, in which is the .map file of my custom map and a .hps of the same name with

void OnStart()
{
}

void OnEnter()
{
}

void OnLeave()
{
}

Inside. I'm not sure if that is correct, I just got it from another thread I read, perhaps I made a mistake on that? But even besides that, outside of the maps subfolder I have custom_story_settings.cfg, of which has this inside.

<Main
Name="Testmap"
Author="A12"


StartMap=Newest map!.map
StartPos="PlayerstartArea_1
/>

Is there anything else I should be doing? Or did I just mess up one of these steps like a complete idiot who will be mocked by all? I wonder...
