This is the code to your doorknocker. Just put the height of what your Doorknocker is, either you have told me in your form or it's usually 500px height if you didn't give me a specific height. Paste this in your headline area. Make sure nothing else is in the box, and replace with code. Ask me if you have any troubles.
