paypal, emails, and forms, oh my

What I thought would be easy enough to do has turned into an insurmountable barrier, so I turn to you, people that know what they're doing, for guidance.

Here's the form I want to make:

<user entered data>
"FREE" or "PAY" submission buttons
if the user clicks the "FREE" button, an email is sent to them and another email is sent to me containing <user entered data>. I've accomplished at least this much so far. However...
if the user clicks the "PAY" button, they are directed to paypal where they complete a transaction, where upon completion, a similar email is sent to them and me containing the <user entered data> but which indicates they paid

I'm new to Joomla, php, javascript, very new to paypal, and even more new to chronoforms, so some dumbed-down, explicit guidance would be very much appreciated.

Hi banister,

Which version of ChronoForms are you using? You can find the version from Site Admin | Extensions | Install/Uninstall | Components in Joomla! 1.5 or Site Admin | Extensions | Extension Manager | Manage in Joomla! 1.6.

This is quite tricky to handle in CFv3 easier in CFv4.
