Welcome to the Monastery, Sandy_Bio_Perl!

update: I found the issue. When $row is populated from the DB, all of the column names get lower-cased. So if you change tGroup to tgroup when accessing it in row, that should fix the problem. /update

What I'd do, is dump out the entire row using Data::Dumper. Add a use Data::Dumper; near the top of the script, and then:

while (my $row = $sth->fetchrow_hashref) {
   print Dumper $row;
    next;
}

...and check to ensure that the structure contains the proper keys and values. Note that the keys in $row are case-sensitive. If your DB has a lot of rows, you may want to replace next with last, especially if you can trigger the warning on the first iteration.
