Correct settings for paypal express with a downloadable product! Help please!

Hello! I have a paypal account and im upgrading to business account and want my client's customers to be able to checkout without a paypal account.

However, what do all these things mean for a downloadable product?

These are the instructions on the side of the admin section for the Payment module. Does anyone know what to set these to if my store is offering just one handbook pdf file download? There is no shipping address, fees, etc. because it's a download.

Please help me findout what to set all these to! Thank you!

If someone could explain all these not just the ones in red. I dont know what any of these mean!!! I just need to sell a downloadable pdf file for $20

Thanks so much

Just leave them ALL at their default settings, except for the things you are instructed to change as listed here: http://www.zen-cart.com/getpaypal

As to your question about zones vs all U.S. ... if you leave it to "none" (ie: no restrictions), then all your U.S. customers should have no problem using it. Unless you have a VERY specific reason for preventing any certain people group from buying, there's no reason to add any restrictions.
