Hi, you don't need the (false) expression in the else statement. That test wouldn't make much sense, as it is testing if 'false' is 'true'. You don't need any expression there at all to catch when both isAdmin and isStudent are false.

var isAdmin = false;
var isStudent = false;

if ( isAdmin === true ) {
    alert('Welcome administrator')
} else if (isStudent === true) {
    alert('Welcome student')
} else {
  alert('Who are you?');
}

Hi Daniella,

You are close, but for the final 'else' statement, you don't need to pass in a value (you passed in 'false'). If the 'if' conditional fails, it moves on to the 'else if.' If that one fails, it will run the 'else' block regardless.

So, all you need is

else {
  alert('Who are you?')
}

Hope that helps. Keep Coding! :)
