Answer 1

You have dozens of typos in there.
First line:
InterfaceINote
should be:
interface INote
(maybe... but even so it makes no sense to me)

You have lots of errors with lowercase and uppercase letters, writing together the keyword and the name, putting a whitespace between the function name and the parentheses that do the invocation...
And the hierarchy of your interfaces and objects is very complex and difficult to understand.
I would recommend to use an IDE program that can help you formatting the code and spotting these syntax errors.
I also recommend that while writing the code, build it up step by step, checking frequently that it's working so far. It is not useful to write a whole bunch of code, if it turns out that most of it is garbage.
