I am following a JavaScript tutorial on the W3Schools website and I have the following code:

```
<html>

<head>

<title>Hello!</title>

</head>

<body>

<script type="text/javascript">
function confirmShow
{
    var r = confirm("Press one...")
    if (r == true)
    {
        alert("Button pressed == OK")
    }

    if (r == false)
    {
        alert("Button pressed == Cancel")
    }
}
</script>
<input type="button" onclick="confirmShow()" value="Show Confirm Box" />
</body>

</html>

```

and whenever I preview it in Coda or in Safari the alert never shows up.

Thanks in advance!
