Assuming you mean `$_->[1]` (wrapping code in `<code>...</code>` tags preserves things like `[]`). It works for me! Perhaps you should show exactly what you tried and how exactly it "didn't work". Unless I state otherwise, my code all runs with strict and warnings	[reply] [d/l] [select]

I am using your piece of code: `if ( grep { $_->[0] eq $name } @names ) { }` [download] It matches 'Jim' for example, but how do I print Jim's number? `print $_->[1];` ?	[reply] [d/l] [select]

I think you haven't thought about this enough. Jim doesn't have a number, he has two. The print above will work in the for loop example I gave in my first reply: `for ( grep { $_->[0] eq $name } @names ) { print $_->[1]; }` [download] Unless I state otherwise, my code all runs with strict and warnings	[reply] [d/l] [select]
