if (count > bgradePlayer.GetGrade() + 4)
{
    player.ChatMessage("Permission".Lang(player.UserIDString));
    return;
}

In function BGradeUpCommand I found condition, that will be never true. This happens because of count variable initialized with zero and never changed before this lines. So GetGrade + 4 (positive number + 4) will be never less than 0. So this if-case looks strange. Maybe I am wrong and someone can explain me why.
Thank u in advance!
