GameUserSettings Compile error

I am making a C++ class to handle the Settings that the user enters. It handles two things: to give the player their measurements based on the US or the Metric system, and whether jokes should appear in the notification box.

Anyway, this is my .h file.

// Fill out your copyright notice in the Description page of Project Settings.

/**

/Zm150

UCLASS()
class ACTIONSOFNIHIL_API UGameSettings :: public UGameUserSettings
{
GENERATED_BODY()

	UFUNCTION(BlueprintCallable, Category="PlayerDefinedGameSettings")
	void ActivatePlayerDefinedGameSettings();
	
	//Settings Variables
	bool UsingMetricSystem = false;
	bool JokeNotificationsOn = true;

};

and this is my .cpp file

// Fill out your copyright notice in the Description page of Project Settings.

void UGameSettings::ActivatePlayerDefinedGameSettings()
{

};

Ignore this question, it was my mistake. It should have been obvious but I missed it. Sorry about that.
