I decided to test my code halfway through and I'm glad I did because something's not right! Here is what I have so far. Why isn't even the first alert popping up?
alert("Let's do some math!"); var visitorAnswer1 = prompt("Give me a number, any number!"); convertedAnswer1 = parseFloat(visitorAnswer1);
var visitorAnswer2 = prompt("Anotha one!"); convertedAnswer2 = parseFloat(visitorAnswer2);
var add = convertedAnswer1 + convertedAnswer2; var subtract = convertedAnswer1 - convertedAnswer2; var multiply = convertedAnswer1 * convertedAnswer2; var divide = convertedAnswer1 / convertedAnswer2;
var message = "Simple math with the numbers" + convertedAnswer1 + " and " + convertedAnswer2 + "</h1>";
document.write(message);

Your alert code is valid so there's something else going on here.
Two things to check first:
- Are your files saved?
- Is your script linked in index.html? (The file doesn't start with the link in place, they show adding it about 10s in to the video.)

I tested it here:
https://www.w3schools.com/js/tryit.asp?filename=tryjs_array
With this code:
<!DOCTYPE html>
<html>
<body>
<h2>Simple Math</h2>
<script>
alert("Let's do some math!");
var visitorAnswer1 = prompt("Give me a number, any number!");
convertedAnswer1 = parseFloat(visitorAnswer1);
var visitorAnswer2 = prompt("Anotha one!");
convertedAnswer2 = parseFloat(visitorAnswer2);
var add = convertedAnswer1 + convertedAnswer2;
alert(add);
var subtract = convertedAnswer1 - convertedAnswer2;
alert(subtract);
var multiply = convertedAnswer1 * convertedAnswer2;
alert(multiply);
var divide = convertedAnswer1 / convertedAnswer2;
alert(divide);
var message = "Simple math with the numbers " + convertedAnswer1 + " and " + convertedAnswer2 + "</h1>";
document.write(message);
</script>
</body>
</html>
And it worked fine.
Go to the link, overwrite the code in the left panel with my code and run it and you'll see.
I hope that helps.
Stay safe and happy coding!

8,056 PointsYou might have to define the converted answer variables or simply assign that value back to the original visitor answer. And you never opened the h1 tag in the message there is only a closing tag
