Hi,

thanks for the link.

I tried to do what's written there but I have (at least) 2 problems. 
Here they are:

1/ I created a "Gift Page" where all my gift products are listed. I can 
add them to the cart, but when I display it, nothing is in there (the 
basket is not empty, as the message "empty basket" is not displayed).

2/ Despite the first error, I tried to complete the order with the gift 
product in it, but I get this error when confirming the order:

Fatal error: Call to a member function modifyRowFromVariant() on a 
non-object in 
/my/host/dir/typo3conf/ext/tt_products/lib/class.tx_ttproducts_gifts_div.php 
on line 110


Why does it display that? Am I doing something wrong?
I'm using the article table, is the problem linked to that?

Thanks

Daniel
