All I know is what I've told you; I can't help more without inspecting the entirety of your code, and I think you'd probably learn the most from working this problem out yourself at this point. If you're still confused, try finding some other tutorials for modding; if you don't understand what the code is doing, try looking for Java tutorials. I hope this helps.
Ok, so, I'm not sure at all what I did, but this time when I loaded into the game, it says 3 mods loaded. The 3rd one is WorldEdit. And, when I do "//" in chat, the WorldEdit commands show up. I have no idea what happened, but this is great!
