That error means that something is nil when it should not be. Unless I have missed it, you have not shown us which line is generating the error. If you cannot work it out from the stack trace post the complete trace here. If it refers to a line in your code then tell us which that line is.. First, though, have a look at the Rails Guide on Debugging which will show you techniques that you can use to debug the code yourself. It is always better to work a problem out for yourself if possible. Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
