I was using spell tomes to test the balance of spells I was considering adding to my mod, doing testing... When I read the books it says I learned the spell, but they never show up in my menu. However when I use "Help" +spell name to find the spell and then use Player.Addspell it says "Spell (spell here) not added. And I have no idea why it won't work. I even created a disposable test character with a new game to see if that would do any good, and it didn't.

It worked earlier, but then after I altered the spells they were no longer addable to the menu for some reason.

You need to select a skill (restoration, etc) under the magic effect window, or make it a (lesser) power.
