  <head> 
  <script Language="LiveScript"> 
  Function RandomNumber () ( 
  Today = new Date (); 
  Num = Math.abs (Math.sin (today.getTime ())); 
  Return num; 
  ) 
  </ Script> 
  </ Head> 
  <body> 
  <script Language="LiveScript"> 
  <! -- 
  Document.write ( "This is a random number:" 
  RandomNumber ()); 
  / / ->
