Data flow
Here's how data flow in the Computed fields add-on works:
- User input - User fills in and submits the form.
 - Computed Fields - Computed Fields add-on takes the user input and processes it using the defined program.
 - Output - Result is returned to JavaScript through the custom key in the Forms API response data.
 - Frontend - JavaScript takes the result and redirects the user to the Thank you page.
 - Thank you page - A block displays the result to the user on the Thank you page.
 - Computed Fields Results block - Computed Fields Results block takes the result using the 
GETvariablees-dataand displays it to the user if the conditions are met. 
Note
Multiple Computed Fields Results blocks can be used on a Thank you page, but only one variable name can be used per block.
