It has to do with the scope of guess. You used my twice. Get rid of that my in "chomp(my $guess = <STDIN>); " and then it's good. The $guess being evaluated in the while() condition is undef because that is what it has been defined to be in that scope. By saying "chomp(my $guess = <STDIN>);" you're saying that this is kind of a new $guess specific to that block, and it doesn't even exist outside of it. -will (the above message is double rot13 encoded for security reasons) Most Useful Perl Modules -strict -warnings -Devel::DProf -Benchmark -B::Deparse -Data::Dumper -Clone (a Godsend) -Perl::Tidy -Beautifier
