Read the error carefully and work out what it is that is nil. If you cannot work it out read the Rails Guide on debugging which will show various ways of finding out what is going on. In particular you can use ruby-debug to break into your code before the failing line and inspect the data to see what the problem is. If you still cannot work it out post the error message and stack trace here. Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
