Problem with returning a user defined class as type

I have a class Multimap and in its private sector I have a node class. (nested)
Also in multimap (public sector) I have a function X that returns a Node type (from my private class).
I get these errors:

error C2143: syntax error : missing ';' before 'tag::id'

error C2501: 'Node' : missing storage-class or type specifiers

fatal error C1004: unexpected end of file found
Error executing cl.exe.

any idea whats going on? I'll include my class files! THANKS TO ANYONE WHO TRYS!

PS its due at midnight tonight ;-))
