Hi,
Thanks for pointing me in the right direction.
I found this bit of code in the cc.php file...

$this->cc_middle = substr($_POST['cc_number'], 4, ($len-8));

I presume this is what gets the middle 8 digits.
I don't know much about javascript (i'm a vb person! lol)...but im thinking something like this should do the trick...

$this->cc_middle = substr($_POST['cc_number'], 4, ($len-4)) + " " + substr($_POST['cc_number'], 8, ($len-4));

Am I close? Can anyone help me out with the syntax if I don't have it right?

Thanks
Rossco.
