If I create several question by "survey tools" , can I calculate and show the summation of the total score after customer submit the selected result(0-5)?

Hello Adams,

Thanks for getting to us! How are you?

It is possible to add the Payment Total Field. On front-end, you will see the calculation based on your Payment field values. Please check the attached file.

Please let us know if you had any other questions at all! Thanks! Have a great day!
