EDIT UPDATED CODE TO REFLECT THE CHANGE!!!
</script>
<script language="JavaScript"> IP = prompt("Please enter IP of Device", "");
document.write("<p></p>Page is now custom for " + IP + ", Enjoy.");
</script>
I am not sure exactly where I am going wrong with the syntax or if I need to declare the value as an html variable and then work from there or what needs to be done ...
Any help would be appreciated!
Thanks
