PlayerInteractEvent

Hello.
When i placing or interacting with block - code works. When i break block - it's not work. Why?
Block position >>4
$cx
$cz
$owner - from cfg owner of chunk
$this->config->exists("$owner") - if owner equals the town he check the leader and if leader of town == our name then he allow to break
$n - name
$p - player
$e - Event
$town - player town

PHP:

        if($this->config->exists("$cx $cz"))
        {
            $owner=$this->config->get("$cx $cz");

            if($owner==$n)
            {

            }
            else
            {
                if($this->config->exists("$owner"))
                {
                    $town=$this->config->get("town$n");
                    if($this->config->get("$owner")==$n && $owner==$town)
                    {
                   
                    }
                    else
                    {
                        $e->cancel();
                    $p->sendMessage("§l§cError");
                    }
                }
                else
                    {
                        $e->cancel();
                    $p->sendMessage("§l§cError");
                    }
            }
        }
        else
