3,423 PointsAdd a final else clause to this conditional statement. If both the isAdmin and isStudent variables are false, the value
const isAdmin = false;
const isStudent = false;
let message;
if ( isAdmin ) {
message = 'Welcome admin';
} else if ( isStudent ) {
message = 'Welcome student';
} else ( isAdmin + isStudent === false ) {
message = 'Access denied';
}

Sonia Nitu
Front End Web Development Techdegree Student 10,852 PointsThis works perfectly in the browser, but not in the challenge. Finally, I have realized the final DOT after "Access denied" was misplaced INSIDE the quote marks, which made all the difference. Frustrating :(. `const isAdmin = false; const isStudent = false; let message;
if ( isAdmin ) { message = 'Welcome admin'; } else if ( isStudent ) { message = 'Welcome student'; } else { message = 'Access denied.'; }`

Treehouse Moderator 37,776 PointsHi Sonia. Yes in challenges strings have to be exact or they won't pass. "Access denied" !== "Access denied."

const isAdmin = false;
const isStudent = false;
let message;
if ( isAdmin ) {
message = 'Welcome admin';
} else if ( isStudent ) {
message = 'Welcome student';
} else {
message = "Access denied";
}

Thank you!

Treehouse Moderator 37,776 PointsYou are welcome. Yes conditions are only for if and else if. Then the else will run if all conditions are false.
if (condition)
else if (condition)

const isStudent = false;
let message;
if ( isAdmin ) {

} else if ( isStudent ) {

}
{isAdmin + isStudent = false} {

}
I am getting and ERROR: "Did you add an 'else' clause to the end of a conditional statement"?

Treehouse Moderator 37,776 PointsHi Shanna. You need to add an else to the end of the conditional statement. :). Hope that helps

} else
{
message = 'Access denied';
}

2,050 PointsHi I am struggling about this exact tusk right now . looks like I am doing everything alright . can you explain my mistake ( isAdmin + isStudent === false ); } else { message = 'Access denied';
Mark Sebeck
Treehouse Moderator 37,776 PointsHi Khatia. So the challenge gives us:
const isAdmin = false;
const isStudent = false;
let message;
if ( isAdmin ) {
message = 'Welcome admin';
} else if ( isStudent ) {
message = 'Welcome student';
}
So I see what you are doing. It's a good try. You are making sure both conditions are false. But you can't conditions like that. The good news is you don't need to. If your code makes it to the else then all conditions above had to be false. So delete this part:
( isAdmin + isStudent === false );
and simply use your else. And don't forget to close your bracket at the end.
Hope this helps.

2,050 Points( isAdmin + isStudent === false ); } else { message = 'Access denied'; }
is this what you mean ? or I do not need to write message = ' Access denied ' ;
Khatia Bagaturia
2,050 Pointsokay I deleted the one you told me and my code looks like this : } else message = 'Access denied'; } still does not run .
Khatia Bagaturia
2,050 PointsThat is how everything looks like right now when I am trying to finish it .
const isAdmin = false; const isStudent = false; let message;
if ( isAdmin ) { message = 'Welcome admin'; } else if ( isStudent ) { message = 'Welcome student'; } } else { message = 'Access denied'; }
and the result is can not read property 1 null
Mark Sebeck
Treehouse Moderator 37,776 PointsYou have an extra close bracket before the else. Delete that and it should work.

Treehouse Moderator 37,776 PointsMark Sebeck
Treehouse Moderator 37,776 PointsYou just need the else like this
the condition is what you had in () after the else
