How to make form calculation widget ONLY numeric?

Is it possible to make form calculation widget ONLY numeric?

Hello asimsidiqi,

Thanks for reaching out to us. Unfortunately, there is no way to make only numeric Form Calculation Widget because Form Calculation Widget is not designed for taking input from the user. You can use Form Calculation Widget to calculate some values from other form fields.

I have checked your form. In your case, you can use Number Form Field instead of Form Calculation Widget. You can add Number Form Field shown below.

Thanks for reaching out to us. Let us know if you need any further assistance.

Thanks for help!
