            //I THINK THE PROBLEM IS AT THIS JS LINE
           // introJs();
            //javascript:introJs.start();
            introJs().setOption('showProgress', true).start();
            </script>
            <?php
            setcookie("userip", "mycookiename", time()+3600);
        }


<script type="text/javascript" src="intro.js"></script>
