I'll keep repeating myself till you get it right : Just use the table definition that's provided in the User Guide instead of manually adding every column the session library needs to your users table.

Those 'undefined variable: .." errors mean you are trying to access a variable that does not exist (yet). But without seeing some of your code it's pretty hard to tell what's going wrong.

Have you ever coded with PHP before? It's essential that you know PHP if you want to use CI! It's just a framework that makes it easier to set up and build your projects, but it doesn't remove the need of knowing how to code in the first place!
