if OptOut isn't passed it, you get under. the following should get rid of
the warning:
my $OptOut = $q->param('OptOut') || '';

that's probably because of the above warning. if the 'OptOut' param is
missing, the warning is send out before you send your header, this mess up
your cgi script. if the 'OptOut' param is passed it, everything is cool.
that's why sometimes you see the error and sometimes you don't.
