Hello, as far as I know, the function .toUpperCase() doesn't take any value inside the parentheses. You can just put var userName = id.toUpperCase() + "#" + lastName.toUpperCase() .It should work.

Hope this helped :-)

Almost! Make the # into its own string, and capitalize the lastName and you have it! var userName = id.toUpperCase( ) + '#' + lastName.toUpperCase( );

Your current result is "23188XTRSmith" instead of the "23188XTR#SMITH" that we want to get.

This is because you are only converting to uppercase the id, but not the lastname.

You could get away with just using twice the toUpperCase method, but a smarter way is to concatenate first and use the method just once on the result:

var id = "23188xtr";
var lastName = "Smith";

var userName = (id + '#' + lastName).toUpperCase();

This way your code has better readability and less operations.
