Okay, I took out the extra space ...

You are interpolating some variables that have an undef
value. The line 10 refers just to the start of the string;
the actual variables are down inside the qq|| block somewhere.
The supposedly undef variables are $ENV[REMOTE_HOST} and
$ENV{REMOTE_ADDR}
I changed them to defined variables (at beginning of code, with new CGI
statement):
my $raddr = $ENV{REMOTE_ADDR};
my $rhost = $ENV{REMOTE_HOST};
and I used the new variables in the HTML.
I am wondering if I should have vars in qq|| or not ... Going to try
using a concatenate method ...
