Only Admin Role Can Edit or Delete Notes Rails 4 - ruby-on-rails

Question

I am having a simple issue but nonetheless unable to figure it out. My employee role can not edit or delete notes but they can view them & they can also create them.
My admin role however can view, create, edit & delete. My employee section is working but my admin is not. I am still new to rails so please bear with my ignorance.
My error is "NameError in Notes#index" and "undefined local variable or method `note' for #<#:0x007fa7b580c0a0>"
In my notes/index.html.erb file my code is as follows:
<% if #user.role == "employee" %>
<%= link_to 'New Note', new_note_path, class: "btn btn-primary btn-lg" %>
<% #notes.each do |note| %>
<div class="row notes-row"><h1><%= note.title %></h1></div>
<div class="row notes-row"><h3>Created By: </h3><%= note.user_name %></div>
<div class="row notes-row"><h6>Posted On:</h6><%=note.created_at%></div>
<div class="row notes-row"><%= note.text_box %></div>
<br>
<p><%= link_to 'View', note %></p>
<br>
<hr>
<% end %>
<% elsif #user.role == "admin" %>
<%= link_to 'Add New Job', new_job_path, class: "btn btn-primary btn-lg" %>
<%= link_to 'Edit', edit_note_path(note) %><%= link_to 'Destroy', note, method: :delete, data: { confirm: 'Are you sure?' } %>
<br>
<p> <% #notes.each do |note| %> | </p>
<%= link_to 'View', note%>
<%end%>
<% end%>
My index method is :
def index
#users = User.all
#user = current_user
#notes = Note.all
#notes = Note.paginate(:page => params[:page],:per_page => 5)
end

Your error arises from this point;
<%= link_to 'Edit', edit_note_path(note) %><%= link_to 'Destroy', note, method: :delete, data: { confirm: 'Are you sure?' } %>
The variable note is unknown at this point.
You could re-factor it this way;
<% if #user.role == "employee" %>
<%= link_to 'New Note', new_note_path, class: "btn btn-primary btn-lg" %>
<% end %>
<% #notes.each do |note| %>
<% if #user.role == "employee" %>
<div class="row notes-row"><h1><%= note.title %></h1></div>
<div class="row notes-row"><h3>Created By: </h3><%= note.user_name %></div>
<div class="row notes-row"><h6>Posted On:</h6><%=note.created_at%></div>
<div class="row notes-row"><%= note.text_box %></div>
<br>
<p><%= link_to 'View', note %></p>
<br>
<hr>
<% end %>
<% if #user.role == "admin" %>
<%= link_to 'Add New Job', new_job_path, class: "btn btn-primary btn-lg" %>
<%= link_to 'Edit', edit_note_path(note) %><%= link_to 'Destroy', note, method: :delete, data: { confirm: 'Are you sure?' } %>
<% end %>
<% end %>
<br>
<% if #user.role == "admin" %>
<p> <% #notes.each do |note| %> | </p>
<%= link_to 'View', note%>
<%end%>
<% end %>
The code can be cleaned up further.
