Hi again Jason,
Another question about 2) :
Ok I get the IPN page ( I did a copy of checkout_success.php page for this use) but how to get the OrderID in the orders table ? I need it to get a RecordSet and set this order to "Paid" in a "paypal" field.
In the variables list, I can get the ID of products (<?php echo $eCart1->DisplayInfo("ID"); ?>) but I don't find the OrderID. Is it possible ?
