I don't understand why this isn't working?!

I am failing the challenge as it tells me the alert does not say 'Who are you?'....

Please help!

script.js
var isAdmin = false;
var isStudent = false;

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

You need to change each boolean value to false and then test that they are both false.

var isAdmin = false;
var isStudent = false;

if ( isAdmin) {
    alert('Welcome administrator');

    } else if ( isStudent) {
    alert('Welcome student');
    } else {
    alert("Who are you?");
}

At the moment you're assigning new values instead of comparing them. But you can compare values by simply omitting them as JavaScript merely has to check the value already in the variables.

If you wanted to explicitly state the value you want to check you'd do

var isAdmin = false;
var isStudent = false;

if ( isAdmin == false) 
...
    } else if ( isStudent == false) {
...
}
