This time I really am stuck...Free Memorization Spell

[Enforcer84]

So I'm adding a few items from Griffen's Saddlebag and the first one...literally the first item in the book...

"if the character knows this wizard spell they can have it prepared for free and it doesn't count towards their daily total of prepared spells."

So...

I'd be looking for a eval script that checks his spellbook (tSplBkExpr?) for the spell, then if the spell is in the book then it gets added to his prepared list

I'm assuming it's possible to check the spellbook but I may be wrong.
