Yes. That fixed my use problems. I am not sure I like the idea of using an
untrusted language. I wonder if it causes a potential security issue.

According to Michael (whose email I can't access at the moment) it has to be
lowercase. I never dreamed Perl would be case sensitive but after changing
the case, voila! :-)

I just tested the untrusted function using a normal user and it worked.

Hmmm well I have this gut feeling that it is better to use a trusted language
than an untrusted one but I have no idea if that is supported by fact. My
inclination is that now that the function is working and tested that I should
comment out the two "use" commands and recreate the function with the trusted
version.
