Subject: undefined method??

When I press MSG or EXIT buttons I get undefined method errrs for the
programs domsg and doexit respectively. They are public methods so they
should be quite visible. Code follows - pls tell what I am doing wrong.
thanks in advance.

class MyForm
  def domsg
     puts "domsg called"
     lbl.configure("text"=>"Goodbye cruel world\nGoing down real soon")
     t=Time.now.asctime
     t=t.split(" ")
     puts t[0]+" "+t[1]+" "+t[2]+" "+t[3]
  end
  def doexit
     puts "doexit called"
     t=Time.now.asctime
     t=t.split(" ")
     puts t[0]+" "+t[1]+" "+t[2]+" "+t[3]
     puts "....going down!.....crash!"
