Validating email address

I want to validate email address (or UPN) in my form.  I did some “google research” and found a script that should do the thing (https://www.w3resource.com/javascript/form/email-validation.php#).


function ValidateEmail(extAccountName) 

  var mailformat = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/



    return true; 




    return false; 




Field name in form is extAccountName, which is created by concatenating a few fields together


"ext-" + [[extUserFirstName]] + "." + [[extUserName]] + "@almamedia.fi"


Calculating the value by first and last name works, but validation doesn’t. It rejects then input in every case. How should I do the validation?
