[SOLVED]Order id in order conformation

[MaartenPol]

I try to show the order id in the subject of the order conformation e-mail. I found in modules/mailalerts/mailalerts.php the following line:

$subject = $this->l('New order');

I tried to change this in

$subject = $this->l('New order') . ' [' . $order->id . ']' ;

No error is show, but I doesn't show the order id in the subject of the mail

Any idea's to get this done?

Well I found a extra space in the line before the last ; That was the issue... Now it works fine
