undefined method error appears in erb but not haml

Hey all, All I wanted to do was convert a haml file to erb. After doing so, i get an undefined method `render_sequence_nav' error message. Even though no such error happened when it was in haml format. I believe the culprit is this line which I am converting incorrectly:

#fields << render_sequence_nav(sequence_info, students_path)

This is what I got:

<%:ruby %> <% sequence_info = {     :label => "Student Fail",     :steps => [ "Select Student", "Enter Criteria" ],     :num_steps => 2,     :selected_step => @step   } %>

<%= render_breadcrumb_trail %>

  <%= render :partial => "resources_partials/sequence/header", :locals => sequence_info %>

    <%= render :partial => "resources_partials/sequence/step_heading", :locals => sequence_info %>     <%= render :partial => "resources_partials/sequence/errors" %>

<% form_for(@student, :url => {:action => :student_fail}, :html => {:id => "sequence", :class => "student fail"}) do |f| %> <%= f.error_messages %>

    <%:ruby %>     <% fields = if @step == 1%>        <%= [ select_tag(:id, options_from_collection_for_select(Student.failed, :id, :selector_label, @student.id), :size => 10) ] %>

     <% fields = if @step == 2%>

        <%= collection_select(:student_fail, :student_fail_state_id, StudentFailState.all, :id, :key) %>        <%= submit_tag 'Submit' %>

        <% end %>         <% end %>

  <div id='fields'><% fields << render_sequence_nav(sequence_info, students_path) %></div>         <% fields << render(:partial => "resources_partials/sequence/nav", :locals => sequence_info.merge({:cancel_url => {:controller => :dashboard}})) %> <%= render_form { fields } %> <% end %>

Any ideas as to what's converted incorrectly? Thanks.
