Problem with array

I have two action in the same controller:

def list
if logged_in?
sort = case params[‘sort’]
when “title” then “title”
when “a” then “a”
when “b” then “b”
when “c” then “c”
when “title_reverse” then “title DESC”
when “a_reverse” then “a DESC”
when “b_reverse” then “b DESC”
when “c_reverse” then “c DESC”
end

if params[:query]==nil
  conditions = ["login LIKE ?", "%#{current_user.login}%"]
else
  conditions = ["login LIKE ? and title LIKE ?",

“%#{current_user.login}%”,"%#{params[:query]}%"]
end
@total = Suma.count(:conditions => conditions)
@sumas = Suma.paginate :all, :order => sort, :conditions =>
conditions, :per_page => @total+1, :page => 1
if request.xml_http_request?
render :partial => “items_list”, :layout => false
end
else
redirect_back_or_default(’/’)
end
end

And I have other action :

def xls

# Creamos un nuevo archivo Excel en disco

workbook = Excel.new("#{RAILS_ROOT}/public/works.xls")

# Añadimos hoja EMPRESAS

works = workbook.add_worksheet("Works")

# Fila de cabecera

@cabecera = %w(title a b c)

columna = 0

@cabecera.each do |cab|

  works.write(0,columna,cab)

  columna += 1

end

# Una fila para cada empresa

@sumas = Suma.find(:all, :conditions => ["login =

?",current_user.login])
fila = 1

for e in @sumas

  # Añado la fila con los datos en sus respectivas columnas

  works.write(fila,0,e.title)

  works.write(fila,1,e.a)

  works.write(fila,2,e.b)

  works.write(fila,3,e.c)

  # Pasamos a la siguiente empresa en una nueva fila

  fila += 1

end

I like when the user puss xls import the @sumas select in the list not
all. Well pass list: @sumas to xls action!!
Thank you!!
