Teaching magic spells through weapons

Ugh, all that frustration and so many attempts and it all boiled down to a typo, where I entered the wrong value by mistake. >:O

Don't worry, we get mistakes like that all the time.With experience you'll be able to detect mistakes quite easily.

EDIT: Hmm... still some difficulties actually. I've gotten it so that AP is gained after battle, and everyone has MP displayed and Magic selectable in their battle menu just as it would be after the event in Zozo.

However only Terra is actually learning the spells from equipment. As an experiment I have it so that the Mythril Knife teaches Libra x2. Terra and Locke are both equipped with it yet only Terra is learning the spell. I have Locke equipped with Ramuh and he can summon him in battle, yet he is not learning any spells.

I'm clueless about this one. Did you check usME?
