Openproject "plugin" I am attempting to create for the first time. Line 13 is where I would like the current project_id from the session variable to print but its not working that way.

index.html

<%
  p_id = nil
  wp_id = nil
%>
  <div class="page-header">
    <a href="/" class="btn btn-default pull-right">&lt;&lt; Return to OpenProject</a>
    <h1 class="">Todo Tasks List</h1>
  </div>
  <% if notice %>
    <div class="well well-danger"><%= notice %></div>
  <% end %>
  Project ID:
  <%= session['@workpackages']['project_id'] %><br />
  <div class="text-right">
    <%= link_to new_todolist_path, class: "btn btn-success" do %>
        <i class="glyphicon glyphicon-plus"></i>&nbsp;Add New Task
    <% end %>
