I need some help. Could someone help me with this code. I need a PHP Script inside this HTML for this booking to send emails properly. Cause it this case it opens a mail program like thunderbird, outlook, gmail and any stuff like this. I really need that the PHP is INSIDE the HTML. I am using software that reads only HTML and JAVA. Thank you.
