Rails - Dec 2010 - Having trouble with CanCan

So I got CanCan and Devise working well. I have two types of users:
Admins and Nonadmins. Admins can edit all of Nonadmins profiles.

The problem is, every user (either Admin or Nonadmin) belongs to an
Account or Organization. Admins should only be able to edit users from
their own Account or Organization. I was able to do that too.

The problem is, I can''t display the links to the edit buttons.
Everything seems fine, I don''t see any errors.

Here is what I have in ABILITY.RB
-------------------------------
    if user.role == "admin"

      # can :manage, :all

      can :manage, Account do |account|
        account.try(:id) == user.account_id
      end

      can :manage, Appointment
      can :manage, Client
      can :manage, Service

      can :manage, User do |u|
        u.try(:account_id) == user.account_id
      end

    elsif user.role == "employee"

-------------------------------
this is what I have on the file that lists the users:
-------------------------------
    <% if can? :update, @user %>
    <span class="span_user_controls">
      <%= link_to ''Edit'', edit_user_path(user) %>
      <%= link_to ''Destroy'', user, :confirm =>
''Are you sure?'', :method
=> :delete %>
    </span>
    <% end %>

Nevermind, I found the problem. I was supposed to remove the @ because 
it''s iterating from a loop:

<% @users.each do |user| %>

<%
    if user.first_name.nil? or user.last_name.nil?
      user_link = link_to ''User Details'', user, 
:class=>''first_and_last_name''
    else
      user_link = link_to user.first_name + '' '' +
user.last_name, user,
:class=>''first_and_last_name''
    end
%>

  <% user_name = user.first_name.to_s + '' '' +
user.last_name.to_s %>

  <div class="div_user">
    <span class="span_name"><%= link_to user_name,
edit_user_path(user)
%></span>
    <span class="span_title"><%= user.title
%></span>
    <span class="span_email"><%= user.email
%></span>

    <% if user.role == ''admin'' %>
      <span class="span_role"><%= user.role
%></span>
    <% end %>

    <% if can? :update, user %>
    <span class="span_user_controls">
      <%= link_to ''Edit'', edit_user_path(user) %>
      <%= link_to ''Destroy'', user, :confirm =>
''Are you sure?'', :method
=> :delete %>
    </span>
    <% end %>
  </div>
<% end %>
</div>
