Thank you very much for your reply.
I'm using Textpad to create the html. When I bring up the html file in Textpad I can't find any characters that look like they don't belong.
However, that was an issue that I ran into on a different site, these tiny ascii square boxes were popping up because sometimes I copy & paste the code from notepad to textpad, or from an e-mail or whatever else. I didn't know that characters could just appear like that. Is there a better program or a way that I can see these undesireable characters to get rid of them?
