cognito-expressions

Build Cognito Forms expressions by applying basic grammar, field referencing, and operators to define calculations. You can implement dynamic logic by utilizing the function library and global evaluation context to process user input accurately.

The Cognito Forms expression library provides functions like SUM() and IF() for dynamic calculations. Using these functions within the global evaluation context allows you to implement conditional field visibility and compute values based on user input.

Conditional logic in Cognito Forms operates by evaluating user input against defined criteria using functions like IF(). This mechanism dynamically controls field visibility and triggers specific calculations within the form's execution context.

You can calculate discounted totals and tax in Cognito Forms by writing expressions that reference state and order amount fields. Applying correct syntax, operators, and conditional logic yields the final computed values for your form.

Cognito Forms calculations often fail due to incorrect syntax, improper field referencing, or misunderstood execution context. Correcting the expression grammar, operators, and function parameters resolves these evaluation errors.
