JavaScript inline code not showing up in browser

Question

I am taking my first JavaScript class. The first two exercises I did worked great. This one however is not. Nothing all all shows up in the browser. It is just a white page. Any suggestions would be greatly appreciated.

<html xmlns="http://www.w3.org/1999/xhtml">
  <body>
    <script type="text/javascript">
      var degFahren = Number(prompt("Enter the degrees Fahrenheit",32));
      var degCent; 
      degCent = 5/9 * (degFahren - 32));
      document.write(degFahren + "\xB0 Fahrenheit is " + degCent + "\xB0 centigrade<br />";
      if (degCet < 0) { document.write("That's below the freezing point of water");}
      if (degCent == 100) { document.write("That's the boiling point of water"); }
    </script>
   </body>
</html>

You have a typo; degCet > degCent in your first if statement. — TylerH

This code should work. These are easy to spot problems, just open up your javascript console (F12) and you'll see you have an extra ) on line 8, and a missing one line 10. There was also a typo on degCent.

    var degFahren = Number(prompt("Enter the degrees Fahrenheit",32));
    var degCent; 
    degCent = 5/9 * (degFahren - 32);
    document.write(degFahren + "\xB0 Fahrenheit is " + degCent + "\xB0 centigrade<br />");
    if (degCent < 0) { document.write("That's below the freezing point of water");}
    if (degCent == 100) { document.write("That's the boiling point of water"); }
 </script>
 </body>
 </html>

@floyd Don't be sorry if you did not know about the javascript console, but always use it in the future, it will save you a lot of time ;)
