    Is it possible to have a total number of units and have it reduced as the form is submitted?

    Asked by selvecchio85 on August 24, 2016 at 08:55 PM

    Is it possible to have a total number of units (say 5) and have it reduced as the form is submitted? For Example:

    5 Units to start
    Person 1 selects and submits 1 and now there are only 4 for the next person
    Person 2 selects and submits 3 and now there are only 1 for the next person

    I know something similar can be done using the calculation widget, but not sure if this can be done exactly like this.

    There are widgets that automatically do this. 

    You can check them here https://widgets.jotform.com/search/registry

    The commonly used is Quantity Registry widget https://widgets.jotform.com/widget/quantity_gift_registry 

    and 

    Inventory widget https://widgets.jotform.com/widget/inventory

    You can test this demo form https://form.jotform.com/61471146729964

    Upon submission, the quantity should diminished.

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