Using the Calculate Rule
Users can create Calculate rules that populate a numeric field by calculating its value based on other fields. For example, a Calculate rule can calculate a camp or conference’s total registration costs by multiplying the number of attendees and the registration fee (17 people at $130 each).
Calculations are limited to numeric fields.
This example has a form with three numeric fields:
- Number of attendees: a numeric field.
- Registration Fee: a numeric field with a predefined value of 150.
- Total: a numeric field where the total will be displayed.
