[Resolveda!]Japanese Script Help

[HarryE]

I need help understanding a Japanese script which, according to a translated description, categorizes the player's items into groups, like "items," "equipments," "important items."

Here is a link to the site;

The link to the sctipt is "samplegame4"

The problem is that I can't understand a thing of it. If someone could please take a look at it and just tell me how to use it, that would be perfect! Thanks =D
