new fields in cart.php and details.php

[adsdc]

Hello,

How can i add the value of a single custom userfield thats used in my registration form to the order information?
I'm using a form to add other users to the cart with jquery that when you click in the button + add a new equal.

I am new to Virtuemart/Joomla.
I'm using the newest version of Joomla and Virtuemart.

Thanks,
adsdc
