Unexpected end of file

[Kyle]

It's alright, I'll find it. You should try to use Notepad++ it makes it a lot easier, but if you're already using it then...

(This may take a few minutes...)

Edit:

(1 minute later...)

Line 20: AddUseItemCallback("Key2Unlock"", "key_tomb_rusty_1", "level_dungeon_1", "LeaveLevel", true);

You added an extra (").

Should be:

AddUseItemCallback("Key2Unlock", "key_tomb_rusty_1", "level_dungeon_1", "LeaveLevel", true);

There would probably be some more errors in there so once you're done fixing that up, tell me what it is if there is one.
