How do you guys remember all this stuff?!?!

Thank you for the reply.
I found both pieces, and it appears there is a variable called $customfields. So I added that to the email content, but the email doesn't include the info yet. Some of the custom fields are designated as hidden and private to the public, so maybe that's keeping the system from including it in my email template?
I'll have to play with this a little, I might be missing something else here, but at least I think you've pointed me in the right direction.
