Hi,
How can I calculate text field value and pass result and the difference to another two text fields, the code I have is not updating when the values changed.

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Untitled Document</title>
<script type="text/javascript">
   function compute()
   {
   var num1 = parseInt(document.form1.fawour.value);
   var num2 = parseInt(document.form1.against.value);
   var computation = num1 - num2;
   document.form1.difference.value = computation;
   if (document.form1.difference.value == 'NaN')
   {
            document.form1.difference.value = '';
            alert('Please enter score');
      }
   }
   function points()
   {
   var num1 = parseInt(document.form1.fawour.value);
   var num2 = parseInt(document.form1.against.value);
    var computation = 1;

       if (document.form1.fawour.value = document.form1.against.value)
      {
        document.form1.point.value = computation;
         }
   }
   </script>
</head>

<body>
<p>
              <form name="form1">

  <input name="fawour" type="text" value="" size="4" maxlength="2">
-
  <input name="against" type="text" onChange="points();compute()" size="4" maxlength="2"/>
</p>
<p>
  <input type="text" name="point" id="point">
  <input type="text" name="difference" id="difference">
                </form>
</p>
</body>
</html>
