Combine and manipulate strings Please HELP

Hey Susanna,

Good to see you're learning JavaScript, it can be a pretty fun experience. Don't worry if you get frustrated at first, when you eventually get it and can build you own programs you'll feel great!

It looks like you're calling the firstname and lastname variables all in lower case, which don't exist because the variables you declared on lines 1 and 2 are lastName and firstName with capital N and JavaScript is a case sensitive language. Changing your msg declaration to this should help:

let msg = firstName + ' ' + lastName + ':' + role;

The result of that should be:

Susanna Clough:developer

You might also want to add a space after the colon ":" like this:

let msg = firstName + ' ' + lastName + ': ' + role;

That way your result should be: Susanna Clough: developer

By the way, the error message you get in the console with the code you had should be something like this:

VM403:4 Uncaught ReferenceError: firstname is not defined at <anonymous>:4:11

This gives you a clue where it says "firstname is not defined" that means the variable you're trying to read has not been declared, so if that ever happens to you again, try looking for the code that's calling the variable and comparing it with the actual variable name to make sure it's declared and being called correctly.

VM403:4 means the error happened on line 4 of your code, in this case, VM403 refers to the console because that's where I tried to run your code, but you'll usually see the file name such as script.js:4 which is useful to help you locate where the error originated.
