Hey friend Fanny Villarosa , you need to put equality === or == operator in place of assignment = operator in your conditional block and then you are ready to go.
Here is the code- 

var isAdmin = false;
var isStudent = false;

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

Also , notice in the challenge , you only need to add and else statement , and need not make any changes in the provided code .
I can see , they have only written if( sAdmin) instead of writing if(isAdmin === true) .
Both are correct , but isAdmin is a falsy value already , so you need not to compare it with true to make it falsy .
There are only 6 falsy values in JavaScript :

  1. false
  2. 0 (zero)
  3. ' ' or " " (empty string)
  4. null
  5. undefined
  6. NaN (e.g. the result of 1/0)

Everything else is truthy
Hope it helped :)
