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)

I converted it to this:
     <% <div id="fields"> fields </div> << render_sequence_nav(sequence_info,
students_path) %>

But Rails says
" syntax error, unexpected '<', expecting kEND
; <div id="fields"> fields </div>...
"
Thanks for any suggestions.

<div id="fields"><%= render_sequence_nav(sequence_info, students_path) %></div>
