Is there a way to have a countdown for tickets?

We are only selling 40 presale tickets - is there a countdown to show that would let others know how many tickets at the presale price are left?

You can achieve this using the Ticket Purchases widget on your form.

Here is a demo form you can test with the widget in action https://form.jotform.com/60130611186949

I hope this help. Let us know how we can be of further assistance.
