Script error, cannot fix whatsoever!

Hi there, I asked a question earlier today about browsers and working in a game, but I received an answer! (Thanks to the guy who helped a lot!~) But I have an issue with it. It gives me an error that I cannot fix. And when I do, it just gives me the same error. If somebody can help, it’s a life saver!

switch (inputField.text.ToLower())
    case "www.blahblah.saq":
        // do something when they hit up www.blahblah.saq
    case "":
        // do something else based off the URL
          // load up the browser image for any "WRONG" URL's

It gives me this error,

You forgot a break after the default case.
