How do I make sure that the purchaser fills out a form for every ticket that they purchase?

If you are setting up an event, and want to make sure that the purchaser is presented with a form for every ticket that they purchase, then make sure that the multi-form filling box is unticked.

On the event page in the administration panel, click on Show in the Options section.  Untick the multi-form filling box.  Scroll down and click on Save.
