Question validation equation:
Question validation tip (nb):
And I think that the Sub-question validation equation is only useful if all the subquestions have the same criteria, etc. all should be email-addresses.
Question validation equation:
(is_empty(kontaktinfo_epost) or regexMatch('/^(\w[-._+\w]*\w@\w[-._\w]*\w\.\w{2,3})$/',kontaktinfo_epost)) and
(is_empty(kontaktinfo_tlf) or regexMatch('/^[\(\)\.\- ]{0,}[0-9]{2}[\(\)\.\- ]{0,}[0-9]{2}[\(\)\.\- ]{0,}[0-9]{2}[\(\)\.\- ]{0,}[0-9]{2}[\(\)\.\- ]{0,}$/',kontaktinfo_tlf))Question validation tip (nb):
{if(regexMatch('/^(\w[-._+\w]*\w@\w[-._\w]*\w\.\w{2,3})$/',kontaktinfo_epost),'Takk, eposten ser riktig ut <br />','Skriv inn en riktig epostadresse.<br />')}
{if(regexMatch('/^[\(\)\.\- ]{0,}[0-9]{2}[\(\)\.\- ]{0,}[0-9]{2}[\(\)\.\- ]{0,}[0-9]{2}[\(\)\.\- ]{0,}[0-9]{2}[\(\)\.\- ]{0,}$/',kontaktinfo_tlf),'Takk, telefon ser riktig ut','Skriv inn et riktig telefonnummer, åtte siffer.')}And I think that the Sub-question validation equation is only useful if all the subquestions have the same criteria, etc. all should be email-addresses.
