[RM2003] SILLY LITTLE ISSUE IN THE DBS I NEED HELP WITH!

Okay, so I've got my game set up where equipping an item to your character will grant said character a skill. The skill is physical in nature and only costs 1 MP, but for some reason, I cannot select said skill in battle. It's greyed out and I can't select it. I have no idea why I can't use the skill either, as everything appears normal in-game. :\

EDIT: It's not skill-specific either. All of my skills that are learned through weapons are doing this. Even when I give the skill directly to the character. :\

Oh for the love of Christ, was that seriously all that was wrong? :D I feel like an idiot, now.

I guess that's what I get for doing CBS's in my serious projects. Thank you so much XD
