Thank you for your reply.
I think that i did not ask the right thing.
In Virtuemart we sell products from other manufacturers with a discount from 40% (for example).
When they bought the product on our site, they have to become a coupon or giftcard with the productdetails and a unique code.
With this giftcard and the code he has to go to manufacurer to become his product.
So i think that i have to make for all products that we sell, a giftcard. If we sell 10 products, i need 10 giftcards.
But If i want to create a gift certicate, there is no dropdownlist by Product! I can't select a product.
Why do i have no dropdownlist?
The manufacturer need also become the mai with the giftcard.
I thought i could fix this with your product, but at this time i don't no how!
