I can't tell if my error is in a different part of the code or if I'm just not understanding the negation operator for the admin part.
<?php
$username = 'sketchings';
//Available roles: author, editor, admin
$role = 'editor';
//add conditional statement
if ($username!='' || $role!='admin') {
echo "You do not have access to this page. Please contact your administratior.";
}

As Mikkel said, you can use isset, but another way to pass this quiz is by just removing the negation operator from the first part of the conditional, so that ($username == "" || $role != "admin").
It's like saying in plain english -> "IF the $username is equal to nothing OR the $role of the user is NOT EQUAL to admin, don't show them the page"

14,421 PointsHey! Thanks for the help. Strangely, after working with my original code, it seems that just adding spaces in the places where you put spaces made it work too (I thought whitespace didn't matter? Maybe it's something to do with how it marks my work...)

Yes sometimes the code challenges can be a bit finicky... And while it is acceptable to not have whitespace between operators and variables, it is pretty common practice to see some spacing, mainly for readability.
