iframe works for one C-Panel folder but not another

Thanks Jacob, I didn’t realize that iframe could only reach an address that included a domain, not just a file path. I solved the problem by creating a subdirectory, games.zafflower.com, and installing a new WordPress site in that subdomain. Now this iframe code will correctly display my Unity3D game. Thanks!
