Hey! So, the problem is how you formulated you string concatenations. There is nothing wrong with the toUpperCase method. If you want to display the value of a variable, you need to leave it outside quotation marks. For example:

let firstName="Pakarang";
let lastName="Buacharoen";
let msg = firstName + " " + lastName;     //value of msg is "Pakarang Buacharoen"

Do you think you can rewrite the assignment to msg that will produce the right string value?

let firstName='Pakarang';
let lastName='Buacharoen';

let msg = firstName +' '+ lastName+':';
let role = 'developer';
let mew = role.toUpperCase();
let mew2 = msg + mew;

The challenge question is

Challenge Task 3 of 3 Finally, convert the string stored in role to uppercase letters. The final msg string should look similar to this: "Carlos Salgado: DEVELOPER".

and once i clicked submit, it shows Bummer: Make sure you're concatenating : to lastName and role.

Great job! You're getting the hang of it. Now, the interpreter is looking at the variable msg for your answer, but you have it stored in a new variable called mew2. Instead of assigning the answer to a new variable, can you figure out how to store it in the msg variable that you've already created? Also, don't forget the space after the colon. ": "
