Como Resetear variable y que queden en Cero

Estimados,

En este formulario:

https://form.jotform.com/240645849204661

Se tiene esto:

en el cual puedo marcar cada campo, pero cuando desmarco uno o mas campos los valores se mantienen y no se resetean (que los valores que no esten marcados siempre sean CEROS), por tanto el TOTAL en este formulario no baja.

Hay forma de manejar esto en Jotform?

Agradezco su ayuda

Hi cuentasdesoftwaregeotravel,

Thanks for reaching out to Jotform Support. Unfortunately, our Spanish Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Spanish, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, let me help you with your question. I checked your form and it currently has conditional logic with missing fields. Please correct this error and try it again.

Give it a try and let us know how it goes.
