Authlogic Facebook Connect/Twitter oAuth helper issues

I am a complete newbie to the world of Ruby & Rails moving from the land of PHP & Symfony. I'm currently attempting to setup the Facebook Connect plugin & Twitter oAuth for authlogic. Authlogic works no problem but both of the others fail when I attempt to开发者_如何学JAVA call their buttons- can someone tell me where I'm going wrong? I've put the stack trace below- thanks!

NameError in User_sessions#new

Showing app/views/user_sessions/new.html.haml where line #13 raised:

undefined local variable or method `authlogic_facebook_login_button' for #<ActionView::Base:0x1034fe9e0>

Extracted source (around line #13):

= f.text_field :password
%br
= f.submit "Login"
= authlogic_facebook_login_button
