Smart fields use a special tag that starts with "$". They cannot be provided by a user in the form. Those fields are build or calculated based on existing nonsmart regular fields.
You can use smart field to do simple and advanced calculations based on provided user form input.
Make sure that you pick “NumberField” in form customization to prevent users from using text instead of numbers for fields that you want use for your calculations.
Smart Fields Numbers vs Strings
If you want to accept strings and convert them into numbers for further calculations (useful if you integrate with the external system) you can use the special syntax within smart fields like : +[fieldname]. Example:
Assuming:
field1: "2",
field2: "5"
field3: 2,
field4: 5
{$ field1 + field2 } ==> 25
{$ field3 + field4 } ==> 7
{$ +field1 + +field2 } ==> 7
// Converts "2" into Number 2 and "5" into 5
Use Special Filters to modify results
Smart Fields for conditions
You can use conditions to output element based on value provided from different field (from user)
