It kind of sounds like a project idea rather than a request for help.
An elevator simulation might make a good project to learn from. It would need a bit more of a spec than create a of elevator program using classes though.
We can't help if we don't know the problem. If you have a problem with your code, post the code and explain in as much detail as you can, what the problem is. Post the error messages if that helps.

Go and mop your fevered brow and pray that tomorrow is a better day than the one you appear to be having today, night/evening or whatever timezone you're in :)
EDIT: Grey Wolf's suggestion makes a bit more sense, it needs more detail though
