Another delete user bug

[Angel]

After I fix this bug I found that on the same page after deleting a user, the input fields in "Manually Add User" section is displaying some weird error notices. So I added these few lines in admin_users.php around line 41:

$username = '';
$fname = '';
$lname = '';
$email = '';

This is inside the delete users if loop that looks like this:
if ($deletion_count = deleteUsers($deletions)){

Then the error is gone. Not sure if this is a good fix. Please let me know if you have a better solution.

Thanks
Angel
