Need help with MarketPress eCommerce.

I'm trying to figure out how to set something up...the product is a ticket for an event.

People buy multiple tickets (products). I would like to get the names of each individual who will be using the tickets.

I had asked people to put it in Special Instructions on the checkout page, but they're NOT <booooo>. Is there another, a better way to get names of who will be using the tickets people are buying?

If they buy 4 tickets, I want 4 names and it must be a required field otherwise checkout will not be done.
