Generate Email from Standard Full Name Field

I have been trying to generate emails from the standard Full Name field, however unsuccessfully. the convention is Firstname.Lastname@domain - this separation of first and last names is what I have been having trouble with.
Any advice will be much appreciated

Hello Maxima People & Culture,

Thank you for reaching out to Jotform Support. I believe this can't be done using the Full Name field. This can be achieved by using a short text entry field for first & last name and then add the Form Calculation widget to generate the email address. It is needed to add a formula in the form calculation widget to concatenate the value of the first & last name with the domain name. Please check the screencast below:
