Thank you for your response, Jaime.
I would love to call it a ticket, but the reason why I’d rather not, is that I have to install and configure WooCommerce or similar products in order to get access to the ticket function. That means more work for me and a more complicated way to manage it for my client. This site is overdue already.
So the perfect way would be if we could call this RSVP a ticket reservation, and then you just pay by the door.
I’m more of a designer than a coder, so I could copy+paste some lines in Custom JS and that’s about as far as I can go with my computer hacking skills 🙂
