About Formula Validation

The formula expression is validated when you update any of the steps of the formula. The current validation status is shown in the Validation Status bar in the Formula Builder. A Validation Status of Green (where the status bar appears in the color green) signifies that the formula is valid. A Validation Status of Red (where the status bar appears in the color red) signifies that the formula 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.
