It is not surprising that you always get :tie if this is the first
line in the method. Go back and look at Michaels code again and pay
attention to newlines. There should be only one 'if' however which
may have confused you. It is important to make sure you understand
code that someone suggests rather than just using it. If you cannot
understand it then work through some Ruby tutorials and if you still
cannot understand it then ask for clarification.

Also both Michael and myself suggested looking at the Rails Guide on
debugging, did you do this? If so what did you learn when you used
those techniques to debug your code?
