Thanks for the reply. Sorry I've been out for a few days.
I've attached a zip file with the application page, which contains the ecart add to cart form, and the confirmation page.
The way this works is that an agent logs in to the members section then accesses the showcase application. The application is basically an ecart add to cart form. So, to answer the first question, they are added to the cart individually.
All of the fields make it to the cart fine except for the image field. Once an application is complete it is added to the cart. There is a button on the cart page that allows them to add another artist application to their cart by filling out another application. This works fine as well, additional artists are added to the cart, but the image field does not get the file name from the additional applications, but somehow is keeping only the file name from the first application.
To answer the second question, the binding is:
<?php echo $WA_DFP_UploadStatus["WA_UploadResult1"]["serverFileName"]; ?>
Anyway, hope this helps. Unfortunately, the site is live and the client does not want the application process interrupted, so I hope the attached files help. Please let me know if other files are needed.
