Step 1: Add appropriate fields to your form. If you want your form to calculate a numbered total, it must contain a form field that can be given a value or perform a calculation, such as a Number field.
Step 2: Select each field to use in the calculation, and assign values in the Field-Specific settings section. If using Dropdown, Checkbox, or Radio Button fields, select Use Separate Values in the Advanced Options Editor to add a value to each option in the field.
Step 3: Click your total field. In the Field-Specific settings section, select Calculation and choose the type of calculation you want to use. Set up your total calculation via the dropdown list of form fields and the numbers and symbols available.
