Switch statement not working

Question

I am working on this code for the switch statement:
<?php include 'list.php';
$status = 'all';
$field = 'priority';
$action = ‘sort’;
$order = array();
if ($status == 'all') {
  $order = arraykeys($list);
} else {
    foreach ($list as $key => $item) {
      if ($item['complete'] == $status) {
        $order[] = $key;
      }
    }
}
switch ($action) {
      case 'sort':
        if ($field) {
          $sort = array();
          foreach ($order as $id) {
            $sort[$id] = $list[$id][$field];
          }
          asort($sort);
          $order = arraykeys($sort);
        }
      break;
}
Everything was working before, and now I am getting the following error:
Notice: Use of undefined constant ‘sort’ - assumed '‘sort’' in /home/treehouse/workspace/todo.php on line 6
The table no longer sorts by priority. 
I have gone through this line-by-line, but I must have missed something. Can anyone offer some guidance?

For some reason the apostrophe for $action is ‘sort’ which is why it is assuming '‘sort’'. 
This has maybe happened due to copying and pasting something.
The correct apostrophe should be 'sort' not ‘sort’.

$status = 'all'; $field = 'priority'; $action = 'sort';

not

$status = 'all'; $field = 'priority'; $action = ‘sort’;

Thanks so much. I have been taking notes and entering code in the workspace, I must have copied code out of word that time. That fixed it.
