Thanks for writing. First, make sure you might be getting the code to the type of web page and software you are running. To make sure you get every one of the code. put your cursor in the box and hit ctrl+A (on a PC), that will select every one of the code, then you can do your ctrl+C to copy then get it to your internet site and paste it in (ctrl+V). Also make sure you're putting it in the appropriate kind of world wide web 'container' specified by Facebook. Superior luck!
