**allfiredupakron**I am looking to take reservations for classes, but want them to have a cap for the number of people that register. I know I can limit submissions, but I have several class options under each form as items for sale (taking a deposit). Can I have them become unavailable after a limit has been reached?

**Deygus**Yes you can, just go back into your Payment Integration and go where your Products are listed then Edit or Add the Quanity field. Under it you will see a " Properties Field " then just click inside the box and edit it by adding or removing the numbers to adjust how many of the product you want to allow to be sold.

**allfiredupakron**Let me clarify, I think that will make me ablle to limit how many ONE person will buy. I would like to limit how many different people can buy, through submitting several different forms. i.e. I have 24 spaces for a class, each person fills out the form seperately, but the form no longer lets them submit after 24 spots are full?

**tomorrownight**Any news on this?

**mert**Hi there,

Unfortunately, we don't have any built-in solution for this one in our payment tools; but you can achieve this scenario by using the combination "Inventory" widget, "Form Calculation" widget and one of the payment tools. Below, you will find a guide about how to do that:

If you stuck or need extra information, please let us know.

Thanks.
