Rails - May 2006 - Using a helper within another helper?

I am trying to push some view logic into a helper.  The thought is that 
this is a step towards having the business logic in the helper rather 
than the view.  However, I''m essentially wrapping the checks around an 
eventual call to date_select().  The problem I''m having is that the 
application complains that it doesn''t know about date_select(). 
I''m
sure (or hope) it''s simple, but so far, I haven''t issued the
right
commands.

To give an example of what I''m doing:
from the view:

    <%= format_planned_start_date @plan, ''plan'',
''planned_to_start_on'',
''Planned Start Date'' %>

and from my helper:

require ''date''

module HtmlHelper
  helper :date_helper
  include DateHelper

  def format_planned_start_date(obj, obj_name, field_name, label)
    text = "<tr><td valign=\"top\"><label 
for=\"#{obj_name}_#{field_name}\">"
    text += "</label></td>\n"
    if obj[field_name].nil? or DateTime.now < obj[field_name]
      text += "<td>"
      text += date_select obj_name, field_name
      text += "</td></tr>\n"
    else
      text +=
"<td><p>#{obj[field_name]}</p></td></tr>\n"
    end
    text
  end
end

The above gives the error: undefined method `helper'' for 
HtmlHelper:Module
I''ve also tried "require ''date_helper''" at
the top and without the
"helper :date_helper" without success.

I''ll still poke at this, but I''m not seeing the obvious
solution.

Answering my own question, I just removed the "helper :date_helper"
and
"include DateHelper" lines and it worked.  I confused myself because
in
earlier version, I had mistakenly wrapped the "date_select" statement
in
"<%= .. %>" tags, thinking it would be re-evaluated.  When it
wasn''t, I
initially assumed that DateHelper wasn''t being pulled in.  When I 
figured out that that wasn''t the issue, I forgot to remove the added 
lines.

Sorry for the noise (but maybe it will help someone else down the line).

It''s always appreciated when you post an answer to a problem, even if
it
is your own question :)
