CTB - A Final Fantasy X-like Battle System, Version 3.2

[Charlie Fleed]

This is an extract from the guide, that explains how to assign skills to categories (or viceversa). Please read this and tell me what exactly isn't clear enough.

Let us assume that you want to create "Black Magic" and "White Magic".
Create two elements named "CMD White Magic" and "CMD Black Magic". For each skill belonging to the “White Magic” category, check the "CMD
White Magic" element. Do the same with "Black Magic" skills and the "CMD Black Magic" element.
Finished. Yes. Simple, isn't it?
Remember: if "Name" is you category, use an element called "CMD Name". "Name" will show up in the command window of the actors, and it will be
displayed only if that actor has at least one skill of that category.

The error is caused by some custom menu system you must be using.
