dont know how to Create a variable named firstName and put your first name in the variable.

script

script.js 
var firstName = prompt ('what is your first name');
Var = message 
message + firstName;
document.write(message);
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>

So first off var firstName = prompt('What is your first name?'); will display a prompt to the user, and will be returned whatever the value the user types, and will store the returned value in a variable called firstName.

Second the line Var = message is actually supposed to be var message; with a semicolon, and the equals should be after the variable name you are declaring, and var should be lowercased as JavaScript is a Case-sensitive language.

third, the line message + firstName; should be message += firstName; or message = message + firstName; The way it is written currently isnt understood by the interpretter, so the first way I wrote it is shorthand for the second way I wrote it, which takes message and sets it equal to itself concattenated with the string of 'firstName'

That should be all the errors you have, I hope this helps, and if you have any questions, just ask. Cheers!
