Keron, Steven is correct, this challenge is asking that you concatenate the strings together into a format like this: "keron veal: DEVELOPER". What you have now just creates a string that looks like this: "undefinedkeronvealdeveloper". So you'll have to do a couple of things to your code here; add formatting to your final msg string to include the spacing and ':' character AND convert the value of the role string to uppercase. Like so,

let firstName = "keron"; 
let lastName = "veal"; 
let role = 'developer'; 
let msg = firstName + ' ' + lastName + ': ' + role.toUpperCase();

Notice that I removed the 'let msg;' code and did not perform a '+=' on it. If you left that in then you'd get something like this: 'undefinedkeron veal: DEVELOPER' as you'd just be appending the value of 'undefined' to the desired message since the 'let msg;' code results in a value of 'undefined'.

You forgot to take away the semicolon after let msg.
let firstName = "keron"; let lastName = "veal"; let role = 'developer'; let msg // ; // msg += firstName; msg += lastName; msg +=

You didn't provide a link to the challenge, but I seem to recall that it wants some spacing and/or punctuation in addition to the words in the final string.

Also, you can't use the "+=" operator until after you have assigned something to the variable you are appending to.

A typical solution would perform all the concatenation on one line, but something like this might also work:

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