Hi everyone, this is my first post and I have a question about the 
goblet of fire in book 4. I'm sorry if this has been mentioned before.

>From what I remember ( I've only read the book once so I can't 
remember everything), it was made clear at the end of the book that 
Moody placed Harry's name into the goblet under the name of another 
school so that he would definitly be chosen as a champion but nobody 
knew this at the beginning. But from what I understand, when you put 
your name into the goblet you also had to put the name of your school 
onto the paper, didn't Fred and George do that? And if that's the 
case then the paper with Harry's name on it should also have the 
school he was representing so it would of been obvious that somebody 
was messing with the goblet.

Just wondering
