==================
Good afternoon, 

In the following question I have entered a validation input to sort of filter invalid email addresses (far from perfection I know). The code I entered in the validation is the following; /^(((\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*(\r\n)?\n?)+)*)$/. In any case, right now if the typing is missing characters such as @ then the help text is highlighted. I would like to simply change the current text "Please check the format of your answer" to "Please enter a valid email address". I want to keep the question non-mandatory as it is right now, so people can simply skip the question if empty and/or non properly answered.

I have tried some other codes but they simply overlap. 



 

so people can simply skip the question if empty and/or non properly answered.

This contradicts the validation. Why do a validation if the respondent is free to enter something wrong?

To enter your own text, use the "question validation equation" and the "question validation tip" in "Logic"
Here you have to use "regexMatch(pattern,question)"

And here you can allow to proceed if left empty
Like:
is_empty(question) or regexMatch(pattern,question)

If you only want to give a hint if the email is not correct without any consequences, insert it either in your question text or in the help text.
Like
{if(!regexMatch(pattern,question),'<span style="color:red">This email is not correct</span>','')}
or something like that.

Many thanks Joffm, 

I would like to simply give a warning, without consequences. Right now, with the validation equation, the respondent gets a warning but he/she can continue. In your equation, should I include the validation code in "pattern" and the Question number replacing "querstion"?

{if(!regexMatch(pattern,question),'<span style="color:red">This email is not correct</span>','')}
or something like that.

Search the forum for "regexMatch" examples

As I understand, there is no good Regex that covers all cases.

I always ask for the email twice. That helps in my surveys, because people will look again. But there are always people that enter valid but incorrect email adresses....
