Creating a "Stat Screen" with assignable points

I was trying to create a Stat Screen with assignable points for my game,
such as the one in “The Great Tournament” novel has.

See link: The Great Tournament

I was looking for instruction in the “Customizing the ChoiceScript Stats Screen” page
in Choice of Games, but I could’t find the instruction for this setting.

Does somebody know where i can find such instructions?

Thank you in advance.

You can find more info on the stats screen here on the wiki.
