  • Single Text Box
  • Multiple Text Boxes

Validating Text Questions

Text questions have a different set of validation criteria. SmartSurvey can automatically check email addresses and numbers for the correct formatting, as well as validating the number of characters or words provided for an answer.

Validating numbers by amount of digits

To validate a number by an amount of digits, set the range to be between 1 (then an amount of zeros which is the required length minus 1) and an amount of 9s equal tyo the desired length. so, for a 7-digit number it shoiuld be between 1000000 and 9999999. This requires that any leading zeros are removed.
