[Typo3-shop] tt_products issues..

[Vladimir Nikolov]

Hi,
I need to implement shopping process, a bit different from the default.
1. When the order is submitted, an email must be send to the merchant. The 
people then have to pay using www.moneybookers.com website.
So I think that I don't want much of the functionality of this shop system, 
only I need to send a mail to the merchant with all needed information. But 
when users have chose the products, have entered the information(address, 
name, etc...) and when he clicks pay/order button, an error message appears 
"You have not filled in all required fields address information. Please go 
back and do that!". All informatin is entered, but this error message keeps 
appearing. I think I saw once a thread in the mailing list about this 
problem, but there wasn't a solution.
2. I need a second price. I found in the documentation how to implement it, 
but now I need "second total price". Do I have to edit the 
class.tx_tt_products.php file or there is another solution?
Thanks in advance.
