I know that upsells are easy enough to achieve in the shopping cart... but for this client solution I'm not using the cart in this one instance.

I know I can create another order form and use its URL in the thankyou URL of the former (thereby chaining them together)

But... and this is the biggy, can I access any of those variables it passes along and use them to pre-populate that linked order form?

I don't want to annoy the client by having them redo all the basic order info...

Thanks in advance for any insights.
