Javascript - string + var alert : <p>I have trouble figuring out why is my alert command not working. I tried looking for an answer in other peoples' questions, but because I am a complete newbie, I was not able to find a solution. My console is giving me this error: practice.js:26 <em>Uncaught SyntaxError: missing ) after argument list</em> . Thank you for any advice. I'm in my first week of JavaScript so go easy on me please :)</p>

<pre><code>var firstName = prompt("What is your first name?");
var lastName = prompt("What is your last name?");

firstName = firstName.toUpperCase();
lastName = lastName.toUpperCase();

var fullName = firstName + " " + lastName;

var fullNameLength = fullName.length;

alert("The string " + fullName + " is " fullNameLength + " characters long.");
</code></pre>
