    How do you decrement quantity on hand as users enter quantities and submit form?

    Asked by Larry Pensinger  on October 23, 2014 at 10:02 AM

    I'd like to offer products of limited quantity and reduce the on hand inventory as users submit the form with a quantity. The updated quantity would then show on the form for the next person to view and order accordingly. At some point the quantity on hand might reach zero and no more would be available.
