error: attribute 'slippi-netplay' missing (HomeManagerModule)

Im not too new to NixOS but I sure suck working with it; as of right now Im having issues using this flake with my home-maanger configuration. I used to get errors about "ssbm-nix" not being defined but I think I fixed that; Now I get slippi-netplay errors.

Here is my configuration:


# ~/.config/home-manager/flake.nix

    # Specify the source of Nixpkgs, get Flake-Utils, & Home-Manager:

Hello, thanks for the response! I've updated the code to be like this now: Now I have a "list" error; did I mess the syntax somehow?
