Aha! I seem to remember that being part of why I made up my own session

What is the security risk attached to having register_globals turned on?

BONUS! Is that a way of saying "if myvar isn't set, set it to zero"?
I hope so because I've got a bunch of pages with the most convoluted
code just to handle that "unset vs. set to zero" issue.

Cool. Thanks.
You just despaghetti'd a mess o' code.
ps. I tantrumed you as a troll about a month ago when an answer you
gave was a little too *personal*. I'm glad I rebuilt my system and lost
my filter.
