Please help!

I keep getting an error because I'm not sure how to combine the iAdmin and the isStudent statements and set them equal to "false". I'm not sure where to start with this so any help may help. :)

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

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

You're actually very close, but the plain "else" doesn't take any conditional clause. It doesn't need one since it handles any case not already covered by the previous "if" and "if else"s.

Also remember to close the last "if else" block with a brace.

You still need a close brace ("}") before the last "else".

The wording of this question makes it sound more complicated than it is, all you need is the 'else' statement since the other options have been checked in the previous statements:

  else {
    alert("Who are you?");
}

Cheers.

Hi Martin,

I copied and pasted your code and I'm still getting an error message. :(

This is what I'm inputting:

var isAdmin = false; var isStudent = false;

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