Hello williamsa16,
Thanks for reaching out to us!
I sincerely apologize for the reply that comes to you very late. We do strive to provide an answer within 24-48 hours to any post. Somehow your thread flew below the radar. Again, I’m really sorry about this and I’ll make sure you will get a timely response from now on.
Our plugins don’t have a built-in functionality like this. I can recommend 2 workarounds.
Create a template override, where the ticket selector cannot go higher than 4. If you tell me what eCommerce solution you are using (WooCommerce, EDD, or the built-in Tribe Commerce) then I might be able to give you some guidance on how to achieve this.
Use WooCommerce and possibly an add-on like this one to limit the max number of tickets. If you go this route then you might need to tweak your site to sell tickets from the WooCommerce products page.
Let me know if this helps.
Cheers,
Andras
