How to make ticket purchase widget mandatory?

Is there some way to make sure a person checks a box on a form?

For example, here is my form to sign up for an ebook promotion.

There are a limited number of slots, so I'm using a Ticket Purchases widget. But I want to make sure that people click on the ticket box before they click on the button below to sign up. I want to make it mandatory, so they cannot sign up unless they tick the box.

You are can simply mark the Ticket Purchase widget as mandatory. To do that, go to the Field Properties, on the General tab select Required dropdown to Yes.

This will ensure users cannot submit the form unless they fill this field. I hope this helps.

Feel free to get in touch should you have further concerns.
