I have FINALLY figured out the DTD issue I had. I decided to use an internal DTD until I have more time to change it to an external one. Externals are better IMO because you can put that DTD anywhere on the server. You can also manipulate easier than an internal DTD. One issue I have with the Topologi DTD checker is that once it sees an error it doesn't take you to it. I have to keep counting spaces over and over again until I found the error.
