Im trying to add extra option in the paypal buttons.

It is for the option of adding domain name user name and password.

No matter how much i tried i never got it to work and though maybe someone who has implemented this into there site may be able to point me how to go about it. I read the instructions but im no good at this html and just spent 2hrs trying to get this to work.

So if someone knows what tag do i use for these options and where do the go in the button.
