About Formula Validation

The formula expression is validated when you update any of the steps of the formula. The current validation status is shown the Validation Status bar, a color bar on the top right of Formula Builder. A green bar signifies the formula is valid while a red bar signifies that it is invalid.

A Validate button is available in the Formula Builder. If you click the button, then you are prompted with the line and place where the error occurs and a description of the error. This button is only enabled when a formula is invalid.
