Sorry for the noobish question but your help would be gold! That depends what you are trying to do. If you explain that we may be able to help. If you do not know what the params hash is all about then you need to work through some basic tutorials. See the rails guides at http://guides.rubyonrails.org/ if you are using Rails 3 or http://guides.rubyonrails.org/v2.3.8/ if using version 2.3.x. Start with Getting Started obviously, then work through the others.
