Hi Hilary,

1st : There shouldn't be a space between .toUpperCase() method on strings and the 'id' variable nor between the parenthesis and the method name.

var userName = id.toUpperCase()

Now, you are asked to concatenate the variables and in between add a '#' in between the lastName & id variables. This is done using the '+' (addition operator) and should look something like this : 

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

Now what's happening here is we use the ' + ' operator to concatenate the variables and the '#' to one string which then is stored inside a variable called 'userName'

Happy Coding

Shay
