ruby on rails - Simple Form drop down menu, string selection -


i use simple form rails 4 app.

i have show page in app identifier location:

<div class="datasubtextq">location:         <span class="datasubtexta">           <% if @project.scope.try(:participant).try(:location_specific) == true %>             <%= render @project.scope.try(:participant).try(:location) %>           <% else %>             <%= render :text => "remote participation sought" %>           <% end %>         </span>   </div>

in form, ask users select location, follows:

                    <%= par.input :location, label: 'where participants take part in project?', label_html: {class: 'response-project'}, collection: [ "brisbane", "melbourne", "sydney" ], prompt: "choose one" %>

when test this, following error:

the partial name (brisbane) not valid ruby identifier; make sure partial name starts lowercase letter or underscore, , followed combination of letters, numbers , underscores.

how ask show form reflect location selection made in form?

thank you

if read error get, can see issue related try render partial not exists , ok, fix issue change 

<%= render @project.scope.try(:participant).try(:location) %>

with 

<%= @project.scope.try(:participant).try(:location) %>
