form error

Dears I''m trying to get a form working in my application however I get
the stack error for this in return.
I allready found out that it''s situated in the def new declaration but
have no clue how to solve this
this is my controller
[code]
require "player"
class SpelersController < ApplicationController

  def index
    @speler = Speler.find(:all, :order => ''RAND()'')
  end

  def all_sorted
  @heren=Speler.heren
  @dames=Speler.dames
  end

  def score_sn
  @senior=Speler.sr
  end


  def score_jr
    @junior=Speler.junior
  end

  def score_p
    @pupil =Speler.pupil
  end

 def score_top
   @man =Speler.topm
  @vrouw=Speler.topv
  end
def new
  @new = Speler.new
end
end
[/code]
and this is my model
[code]
require

end
[/code]
my form looks like this
<h1> Een nieuw lid toevoegen</h1>
<%= error_messages_for ''Speler'' %>
<h1>Nieuwe speler</h1>

<%= error_messages_for :speler %>

<% form_for(@new) do |f| %>
  <p>
<p>
name:<br />
<%= f.text_field :naam %>
</p>
<p>
achternaam:<br />
<%= f.text_field :achternaam %>
</p>
<p>
Score:<br />
<%= f.text_field :score %>
</p>
<p>
score:<br />
<%= f.text_field :ploeg %>
</p>
    <%= f.submit "Create" %>
  </p>
<% end %>

[/code]
I know the create part is not mentioned in the controller but since I
first would like to solve the stack error I left this out.
this is the stack error

 SystemStackError in SpelersController#new

stack level too deep
