I apologize for not being more specific. The cookie IS set before the HTML tag. This is how it has always been set, but on multiple computers I'm still not getting an output. I have just discovered, however, that it might be a server issue, as when I put it on another php-enabled server the cookie IS set.
The server info can be found at:

Not maintaining the server myself, is there something I need to tell the system administrator to turn on/off?
