how validation is done using wicked?

I have a users_controller and a user_steps_controller which has three steps :business, :payment and :login

In the user.rb model

class User < ActiveRecord::Base
validates_presence_of :fname, :lname, :email, :mob, :country, :state, :suburb, :postal ,:add
end

while checking validation if i put some random values then also it is giving errors

Fname can't be blank
Lname can't be blank
Email can't be blank
Mob can't be blank
Country can't be blank
State can't be blank
Suburb can't be blank
Postal can't be blank
Add can't be blank

Please help me out
