Hey Gena,

The else block does not take any parameters. Secondly, isAdmin and isStudent are assigned the value of false to start with. So you can just use an else statement.

It reads like this: If isAdmin is true, alert 'Welcome administrator'. Else if isStudent is true, alert 'Welcome student'. Otherwise, alert 'Who are you?'.

Simply:

var isAdmin = false;
var isStudent = false;

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