Hello Muhammad,

The alert needs to go in between your script tags, like this:

<script>
    alert("Warning");
</script>

That way, the browser knows that the code between the script tags is JavaScript. Outside of these tags, it will think your code is either HTML or regular text.

In your example, you put the alert after the script tags (so HTML doesn't know it is part of a script). Also, you have two closing script tags </script> and only one opening <script> tag, so there is a mismatch there.

And at this stage, you don't need a script source, because you aren't putting your code in a separate file. You can keep it very simple for this challenge!

I hope this helps! Let me know if there is still any confusion.
