Here's my code, it doesn't work...

let firstName = prompt("What's your first name?");

let lastName = prompt("What's your last name?");

let fullName = ${"firstName"} + + ${"lastName"} let upperCaseName = fullName.toUpperCase()

let fullNameLength = upperCaseName.length()

alert(The string${upperCaseName}is${upperCaseName.length}number of characters long.)

Update: I removed the template literals and simplified my code...

let firstName = prompt("What's your first name?");

let lastName = prompt("What's your last name?");

let fullName = (firstName + " " + lastName).toUpperCase;

let fullNameLength = upperCaseName.length;

alert("The string "+"fullName" +" is " + fullNameLength + " number of characters long.");

Hey Kimberly Kohel-Hayes , so first of all in the third line you actually have to invoke the toUpperCase function with parentheses like so:

let fullName = (firstName + " " + lastName).toUpperCase();

In your fourth line you'll realize that the "upperCaseName" variable doesn't exist anymore after you refactored your code so you cannot pull the length from a variable that doesn't exist. Instead you will want to try something like this:

let fullNameLength = fullName.length;

So your final code should look like the following:

let firstName = prompt("What's your first name?");

let lastName = prompt("What's your last name?");

let fullName = (firstName + " " + lastName).toUpperCase();

let fullNameLength = fullName.length;

alert("The string "+"fullName" +" is " + fullNameLength + " number of characters long.");
