Need some help with listing user profiles data [SOLVED]

<?php
$userGroup = $modx->getObject('modUserGroup', array('name' => 'Germany'));

$users = $userGroup->getMany('UserGroupMembers');

foreach ($users as $user) {

   $profile = $user->getOne('Profile);

   /* do display stuff here */
  $fullName = $profile->get('fullname');
  $email = $profile->get('email');

}

<?php
/* build the query */
$c = $modx->newQuery('modUserProfile');
$c->select(array(
   'country',
   'city',
   'GROUP_CONCAT(fullname SEPARATOR "--")',
   'GROUP_CONCAT(CAST(internalKey AS CHAR))',
));
$c->where(array(
 'internalKey:!=' => '1',
 'blocked:=' => '0',
));
$c->groupby(city);
$c->prepare();
 //print $c->toSQL();  (for Debug)
$c->stmt->execute();
$checkcountry=''; //for checking dublicate countries

while ($row = $c->stmt->fetch(PDO::FETCH_ASSOC)) {
$combineddata= array('city' => $row[city], 'user'=>$users=explode("--",$row['GROUP_CONCAT(fullname SEPARATOR "--")']));
//checking if country is already listed
     if ($checkcountry != $row[country]){
     echo "<strong>". $row[country] ."</strong>";
     }
     //looping through combined data array
     foreach ($combineddata as $key=>$value){
          // checking if value is array for listing users
          if (is_array($value)){
          //$value if array - listing users
              foreach ($value as $user){
              echo "<em>".$user."</em></br>";
              }
          } else {
          // $value is string - listing cities
          echo $value."</br>";
          }
     }
//assigning value for current country
$checkcountry=$row[country];
}
