I can't understand the task. Validate by editor or author, editor, admin? I get the message: Use negative operator.

This is what I have: //add conditional statement if (isset($username) && $role <> "admin"){ echo "You do not have access to this page. Please contact your administratior."; }

index.php 
<?php
$username = 'sketchings';
//Available roles: author, editor, admin
$role = 'editor';

//add conditional statement
if (isset($username) && $role <> "admin"){
  echo "You do not have access to this page. Please contact your administratior.";
}

Hello there! Thank you very much for the help. It worked. I could swear I tried " !=, !==, !=== and <>" all the possibilities . Small problem but great help.

Thanks again

Hi Claudio, It's rather an easy problem to solve. They are asking you to check a statement with 2 conditions.

if a username is set AND the role of admin is not equal to 'admin' then echo blabla. You need to use a logical operator in this case you'll have to use != because you want to echo a message that says you are not allowed to acces the page because you're no admin. != stands for not equal to and is the negative operator you are looking for

Example: if (isset($username) && $role != 'admin') echo stuff in here
