Compared with non class/module error

I'm trying to limit the number of albums a user can create by only showing a link to a new album if the number of albums is greater than 3. The error I am getting says 'compared with non class/module'

<% if @albums < 3 %><div class="all-albums" id="position-albums"><%= link_to 'New Album', "/albums/new", :style => "text-decoration:none; color:black; font-size: 20px;" %><div class="plus-sign"><%= link_to '+', "/albums/new", :style => "text-decoration:none; color:black; font-size:80px; color:#85adad;" %></div></div><% end %>
