Question has the server software been upgraded ?

Older php intalations ran with Globals=On
New php intalations run with Globals=Off for security

And reading your post again, think that is the most likely cause of your difficulties.

If it is you script will have to be rewriten, not really to big a deal just adding a few lines to each to get user varables.
