lat9, This is a great mod.
I am getting an error with customer file uploads (product attribute).

If a customer adds to cart
Product 1 with file "a" attached
Product 1 with file "b" attached

The order process returns a blank page once you attempt to pass the order confirmation page and place the order. everything looks great on the final confirmation page but the order is just not going through.

Do you have any idea why?

Thanks,
Mel
