    Hi Elease,

    Thanks for reaching out to Jotform Support. Currently, Jotform does not have a specific setting to restrict or allow negative numbers directly in number fields. But you can allow users to manually enter negative numbers by using a Number field or a Text field with custom validation or calculation logic. But can you give me a few more details so I can understand what you need?

    In addition, could you share the form URL so I can check and have a better idea? You can easily find your form's URL in Form Builder. Let me show you how:

    1. In Form Builder, in the orange navigation bar at the top of the page, click on Publish.
    2. In the Quick Share tab, click on Copy Link in the Share With Link section.
