Hi I have an issue of email-validation script I found, I think its few years old but anyway... I am newbe to making surveys so bare with me. It might not be a new topic for all of you that got a hang of it

I have simply two Multiple short text (Type: Q) to comfirm an input of emailaddress, but it will not confirm its correct. I need a little assistance to make it work, I dont understand whats wrong..

RegExp:
Sub-question validation equation:
Sub-question validation tip:
Thanks in advanced!

Over the last ten years so many people asking for a way to validate email-addresses.
I cannot recommend to implement a sophisticated routine via RegEx. You will prevent someone to enter the valid email-address and still allow fake email-addresses.

You might export a LSS and attach it here for easier debugging.
If your question is called Q00, the subquestion check for identical input in SQ001 and SQ002 could be validated with this
((( ! is_empty(Q00_SQ001.NAOK) && (Q00_SQ001.NAOK == Q00_SQ002))))

If this works, you can expand it with your fancy RegEx.

When your Questioncode is Q00, "this.NAOK = "SQ001" translates into Q00_SQ001.NAOK = "SQ001". Which would only be true if you type "SQ001" as the email.

Hi,
I agree with @jelo about the usability of regex to check valid email addresses.

To explain more:
You have two conditions:

1. Matching emails: this is a question condition
2. Correct emails in each of the two entry fields: this is a subquestion condition

For the first:
In "question validation equation"
(is_empty(self.sq_SQ001.NAOK) || is_empty(self.sq_SQ002.NAOK)) && (self.sq_SQ001.NAOK == self.sq_SQ002)
and a tip

in "subquestion validation equation" (this expands to the QCode of the subquestion)
is_empty(this) or regexMatch('/^.+?@.+?\..+$/',this.NAOK)
and a tip
