CBSubs form? You mean on the credit card page or invoice page? CBSubs doesn't handle registration, CB does. Are you wanting to populate a CB field on registration? Please be more specific as to what you're wanting to do.

I see, you can use CB Auto Actions with the before registration form display trigger in a Code action. You'll want to set the mode to jQuery then use AJAX to call your app server and update the fields input once the AJAX call completes.
