> sorry everyone, I figured it out on my own ;)

So having made it a tutor topic, please close the discussion
by telling us what was wrong. That way the rest of us don't
spend the rest of the day worrying about it, saying
"I wonder what Jason did wrong?" :-)

Sorry if I appear to nag but its how these mailing lists
work - someone posts a problem, everyone looks at it and
everyone should see the answer. That way *everyone*
improves their chances of not making the same mistake.
