Mozilla / mm_menu.js problem

ello,

I have a javascipt menu that works fine in IE but the links don’t work in firefox/safari. To see what I mean: http://online.thepurplebook.com

The script works with the mm_menu.js file. Anyone know of any issues?

The javascript console gives me the error in line 485, of the mm_menu.js file:

function onMenuItemAction(e, l) {
l = window.ActiveMenuItem;
if (!l) return;
hideActiveMenus();
[color=Red] (line 485)[/color] if (l.mmaction) eval("" + l.mmaction);
window.ActiveMenuItem = 0;
}

Thanks vmuch in advance,
Eric
