How can I set available quantiy limits for each ticket item in Payment Form

We want to set the adult tickets limit to 100 and the childrens ticket limit to 40.

Unfortunately, you cannot set different multiple limit on quantity available for the items when using the regular Payment tools.

The quantity limit you can set is only up to 1 for every submission.. that is by not including the Quantity option.

What you can try also instead is using the Purchase Tickets widget as your custom payment form.

The only lacking in the Purchase Tickets Widget is, you cannot assign a custom Quantity option. So, the end-user will not be able to indicate a number of tickets to purchase on a submission.

BUT it will work for limiting the available quantity/inventory of each item/ticket.

Hope this help. Let us know if you need further assistance.

Thanks.
