[xsl] XSL not working in Firefox

[David Lee Heyman <david@xxxxxxxxxx>]

I'm trying to figure out what the problem is with the attached XSL 
file so that I can either write a Greasemonkey extension to fix it or 
get the owners of the site to fix it. In MS IE people can get in and 
see their frequent flyer points but in Firefox and Safari we can't. I 
can't for the life of me find the problem.

The files in question are at:

XML: http://tinyurl.com/c4zbr
XSL: http://tinyurl.com/bu8l2

Any ideas?

David
