Hi Malcolm. You are overthinking it, You simply need to add .toUpperCase() to the role in the msg string. So the end of your msg should look like this:

 + role.toUpperCase();

Hi Mark,

let firstName ="Billy"; let lastName = "White"; let role = 'developer';

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

Error Message for the first: Bummer: Make sure you're concatenating : to lastName and role.

let firstName ="Billy"; let lastName = "White"; let role = 'developer';

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

Error Message for the second: Bummer: Use the .toUpperCase() method to convert the role string to all upper-case.

Both of these outputs as strings are not working. Weird.

Third option is to create a new var let role_2 += role; But you can't modify the 'role' variable inside the string (i.e.original role.) I am going over to freeCodeCamp and practice. Thanks for your help.

Billy I’m just looking at this on my phone but I think you just need a space after the colon and delete the period at the end. The challenges are very picky and you have to have strings exactly the way they want or they won’t pass. Good news is you understand the code part. Keep at it!!
