I hope someone here can help me figure this out, 'cause I've been working on it
for a solid week and can't find the issue. I have a menu that's populated by
XML that will need to go to three levels. When it's populated up to the
secondary level, it's mostly fine, but populating the tertiary level makes the
whole thing blow up in my face. Here's the code (minus the showMenu() &
buildLinks() functions, which aren't relevant to this problem & would only
clutter this up :) ):

trace("xml load failed");
return;
