Before you attempt to solve such issues I would make sure you have a good understanding of the basics of Rails, as you may well decide the above is not the best way to solve the problem. I suggest you first work right through a good tutorial such as railstutorial.org (which is free to use online) including doing all the exercises. Then reconsider your problem and come back with further questions if necessary. Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
