    I would like to create a number field that depends from another field....

    Like; the number is 30, but everytime that somebody subscribes, the number goes down, until it will be 0.

    How can I do this.

    Thanks for contacting us.

    Let me inform you that such function that can allow you to decrease the number of a certain field is not part of our form builder feautures, however, you could be able to add such function by using your form source code and applying some Javascript, so, it would be a change out of jotform. You can learn how to get your form source code following this guide: How to get your form source code
