The code works fine and all, but it clears itself. Any ideas on how to stop this?
Code:
<form method="POST" onSubmit="calc()" name="berechnung">
   <table border="0">
      <tr><td>First Number:</td> <td><input type="text" name="breite" /></td></tr>
      <tr><td>Second Number:</td> <td><input type="text" name="zoll" /></td></tr>
      <tr><td>Result:</td> <td><input type="text" name="durchmesser" /></td></tr>
      <tr><td><input type="submit" value="Calculate" /></td></tr>
   </table>
<form>
<script type="text/javascript" language="javascript">
   function calc(){
      var breite = eval(document.berechnung.breite.value)
      var zoll = eval(document.berechnung.zoll.value)
      var durchmesser = (breite) + (zoll)
      document.berechnung.durchmesser.value = durchmesser;
   }
</script>

You named the var the same as you called the id. Collision.

That doesn't explain why it disappeared.
