Using JavaScript to Show an Alert
In PHP, variable names must start with a $, but that isn't the case in JavaScript. Take a look at the following example, which uses a variable named myText to customize the text that's displayed in the alert box. <script> function showAlert() { var myText = "This can be whatever text you like!"; alert (myText); } </script> Try modifying your showAlert() script with your own custom alert message.

alert("HELLO");

Unlike VBScript, JavaScript requires parentheses around function calls.
Therefore, you need to write alert("Hello!");
It's also preferable (but not required) to end every statement with a semicolon ;.
Finally, if you aren't already, you need to put it in a script block, like this:
<script type="text/javascript">
alert("Hello!");
</script>
You can put JavaScript inside a script tag in an HTML page, or you can make a standalone .js file and double-click on it (in Windows) to run it using WSH.
