Thank you for the help FireFly. I figured it was some kind of a problem with cookies, but I wasn't really sure... That's why I decided to ask someone that was smarter than me.

I tried it with SSI, but I don't
think you can use SSI to include something on a different server. I could just be doing something wrong though. If it is actually possible to use SSI to include files from another server please let me know and I'll see if I can figure out what I'm doing wrong.
I'm not very familiar with the iframe, but I'm sure I can find some sort of tutorial. I'll look that up tomorrow.
Again, thank you for the help.
