I'm having trouble solving this.

Not sure what I'm doing wrong.

app.js
let firstName = 'Jeremy';
let lastName = 'Mao';
let role = 'developer';
let msg = firstName + ' ' + lastName + ': ' + role + '.';
let msg = role.toUpperCase();

There are 2 issues with your code. First, you are concatenating a period on to the end of role. You don't want to do that. Then, you are changing the entire msg by setting it equal to role.toUpperCase(); in your last line. Get rid of that line, and only apply the .toUpperCase() method to the role variable that is already part of your msg string. The value in the role variable will be capitalized and concatenated without you needing to add an additional assignment.

If you still need help, reply to this message and I'll clarify, but I think you can get it from here.

Yes, Jason is correct. You are reassigning the variable msg every time you use the keyword let. If you want to concatenate to the variable, just use the name and don't reassign it. Here's a hint. The value of msg when this program runs is just "DEVELOPER".
