Error Functions are used in displaying a message to the respondent that a question has not been completed properly and that they must remedy the problem before continuing. The Error Functions only work when specified within the Compose | Survey Settings | Error Messages tab.
These functions are different than other Sawtooth Script. See Location Specific Functions.
