How do I setup the payment section in my form?

Please walk me through the following: 

Trying to set up a online registration form for a local 5K. need to be able to accept payments and/or paypal information for the registrations. 

How do i set that up? Where does the money get routed to and how do i ensure a emailed receipt goest to registrant. 

Your form is currently integrated with Paypal. You have a Registration Fee option with a quantity selector. The payment section is properly configured as far as I could see it.

The money will go straight to your Paypal account, assuming that the transaction is completed by the submitter. Note that we don't take a cut or charge you for every transaction made in the form. As for the receipts, they should get one from Paypal. But you can create your own through our auto responder feature.

The autoresponder email can be styled to look like a receipt.
