to clarify on my answer from earlier

Use the JavaScript .toUpperCase( ) string method to assign an all uppercase version of the id variable to the userName variable.

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

var userName = id.toUpperCase();

Finally, add a # symbol and lastName in uppercase to the end of the userName string. The final value of userName is "23188XTR#SMITH".

they are asking you to do string concatenation

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

var userName = id.toUpperCase();

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

toUpperCase is a method and does not require you to put the string in the parentheses. you need to call the method on the variable

you dont need to include the string inside of the parenthesis.

because you are calling the toUpperCase method on the variable id

if you were to write

var username = id.toUpperCase();

it should work

hope this helps
