[jQuery] Tooltip function not working

[jQuery] Tooltip function not working


Am I doing something wrong, or does the tooltip plugin not work with
the latest jQuery?
I have it loaded on my site, and the only code I have is:
$('a.showtip').Tooltip({
        track: true,
        delay: 0
    });
The hover doesn't show in FF or IE, and I get an error in IE:

Any ideas would be appreciated!
Thanks!
