the error message keeps saying i am hitting a null... i need to add the method to uppercase and come out w/ the message

i cannot seem to stumble upon the right answer i have tried doing all this in order and the error says null something...

app.js 
let firstName = 'Carlos';
let lastName = 'Salgado';
let role = 'developer';
let msg = firstName + ' ' + lastName +':/' + role; 
console.log("Carlos Salgado: developer");
let role = "developer";
role.toUpperCase();
console.log("DEVELOPER");
let msg = Carlos Salgado: + let role;
console.log ("Carlos Salgado: DEVELOPER");
let msg= "Carlos Salgado: DEVELOPER";

:bookmark: Hi, I got tagged by "ask to answer". For Task 2, your code might look like this:

let firstName = 'Christine';                         // task 1 said use your own name
let lastName = 'Marshall';
let role = 'developer';
let msg = firstName + ' ' + lastName + ': ' + role;  // needed a space instead of '/'

Then for task 3, the instructions say to "convert the string", so instead of adding more code, you will just change the last line so that it upper-cases the "role". You will still use variables instead of fixed strings:

let msg = firstName + ' ' + lastName + ': ' + role.toUpperCase();  // small change to last line only

And you don't need to log anything for this challenge.
