To get rid of the warnings, you can write `if (defined $data{$key} && $data{$key} eq $input) { ... }` [download] Also, please do read, understand and apply Writeup Formatting Tips. Perl 6 - the future is here, just unevenly distributed	[reply] [d/l]

The OP wanted to type apples for example and have it say "fruits". To do this you need: `if ( $key eq $input ) { ... }` [download]	[reply] [d/l]
