hook error

[Cubeboy]

We have started our sales department for our company we grouped them under 'inside sales' I would when they log in they get redirected to their sales page. I tried to do  a hook and even have tried to user a user name as well. I rather get it to work with one one variable and it works depending on the 'Administrator Roles'

 

<?php
add_hook('AdminAreaPage', 1, function($vars) {
    $extraVariables = [];
    if ($vars['filename'] == 'addonmodules.php?module=metrics') {
        $extraVariables['admin_username'] = 'djone'
else
       $extraVariables['administratorroles'] = 'Inside Sales';

    }
    return $extraVariables;
});

Thank you for all your help in advance....
