 We’ve contacted the following references you provided to verify the work history information you gave as part of your QTS application.
 
-<%= @reference_requests.contact_name %>
+<% @reference_requests.contact_name.each do |contact_name| %>

 They need to respond by <%= @reference_requests.first.expires_at.to_date.to_fs %>. If your references do not respond, and, as a result, we cannot verify your work history, we may not be able to award you QTS.
