Am I able to cap the tickets in an inventory via your form?

Hi, we are selling tickets to events, but there are only a limited amount of tickets on sale. Am I able to cap the tickets in an inventory via your form, making the option unavailable once all tickets are sold?

Yes. You may use the Inventory or Gift registry widget to achieve your requirement. Once the set quantity is over on the widgets, the users will not be able to choose an option from the tickets. Please give it a try and let us know if you need any further assistance. 

On a side note, we notice that your forms are associated with a guest account with a limit of 20 submissions per month. We highly recommend you to create a free JotForm account that helps in managing your forms by logging into your JotForm account and increase the submission limits to 100 per month. You may create an account using the same email address so that the forms shall be automatically moved to your account.

Thanks!
