here is the html: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Practice JavaScript Variables</title> <script src="practice.js"></script> </head> <body>

</body> </html>

and here is the Java:

Looks like your alert() function is missing a double quote right at the start of your first string-

You wrote:

alert(The string \"" + fullname + "\" is " + fullname.length + " characters long.");

It should be:

alert("The string \"" + fullname + "\" is " + fullname.length + " characters long.");

Hope this helps! ^^
