It doesn't seem to like this line above. I get:
======================================
$ perl test.1800HG-v00b.pl > test.html
Use of uninitialized value in hash element at test.1800HG-v00b.pl line 41.
Use of uninitialized value in hash element at test.1800HG-v00b.pl line 41.
======================================

Should I email you (off list) the complete html page that it spits out?  Maybe

Thanks again for your help.
