Rails - Sep 2009 - link_to_function variable increment

My view looks like this
 <%count=0%>
  <%=link_to_function("add another", nil, :id =>
"more_link") do |
page|
    page.insert_html :bottom, ''phone_numbers'',
add_phone_field(count
+=1)
  end
%>
add_phone_field is a helper method.I need to increment count on every
click.But my code above does not do that.
Once count gets the value 1 it remains one.
How can I increase the value of count on every click.


My helper method :
  def add_phone_field(num)
      html=%{<div id="phone#{num}">
<label for="contact_phones_phone_number">Phone
number</label>
      }
      html<< (fields_for :contact_phones do |ff|
          ff.text_field :phone_number,:index=>num
        end )
      html<<link_to_function("delete",
"$(''phone#{num}'').remove()")
      html<<%{</div>}
  end

Classic problem, please see
http://github.com/ryanb/complex-form-examples/tree/master and this
http://sifent.com/blog/2009/05/28/rails-nested-forms-jquery/

Essentially, what you need to do is, use :child_index =>
''NEW_RECORD''
and on click replace NEW_RECORD by some unique number (time will be
most appropriate) using javascript.
