Hash.where did it go?

Rails
1

Hi everybody.

I am really struggling here.please help.
I created hash values in controller and want to send to the view.
I tested out the values in the controller, the values printed out
successfully in my log file
But then when i passed it to view, it printed out nil or no values.
Ive tried using array, same result.
Did i miss something. Please help.

Here 's my controller

##############################controller#################################
def stats
@cus_t = Hash.new

  a = Gruff::Bar.new('500x350')
  a.theme = {
    :colors =>
    ['#138F6A','#330000','#0aaafd','#FF0000','#00CD00','#ff6602',
     '#3bb003','#1e90af', '#efba30', '#0aaaac'],
    :marker_color => '#aaa',
    :background_colors => ['#eaeaea', '#fff']
  }
  a.hide_title = true


  @customer = Customer.find(:all)
  @customer.each do |custs|
  @g_cus = Casedf.count(:all, :conditions=> "customer_id=" +
           custs.id.to_s)
  a.data(custs.companyname, @g_cus)
  @cus_t[custs.companyname] = @g_cus
  @cus_t.store(custs.companyname,@g_cus)

  end

  a.write("#{RAILS_ROOT}/public/images/customer.png")
  $logger.info("hash keys #{@cus_t.keys}")

<%end%>

<%=@cus_t.inspect%>

No customer added so far<%=@cus_t.keys%>
