Hey Guys, I really need your help

 

I'm programing a custom Recipe Hander, who can handle item crafting, Class crafting(Items which are instanceof any class) and crafting with nbtTags. But my problem is, in the program code is a mistake, or more, I don't really know, but I'm stuck. I searched them for like 5 hours now, but I cant find it(or them).
