G'day almoodie,

There seems to be a few things you haven't really understood here:

• @nametape is an array of arrayrefs.
• When iterating through @nametape with foreach, each element will be an arrayref, not a line (i.e. $line is not what its name suggests).
• split operates on a string. Such a string might often be found in variable called $line - but not today :-(
• To access elements of an array you use $array[index]; for arrayrefs, you use $arrayref->[index] (where index evaluates to an integer).
• Had you added "use strict;" and "use warnings;" to the start of your code, Perl would have alerted you to these types of problems. See strict and warnings.

Here's an example of the type of code you need:

$ perl -Mstrict -Mwarnings -E '
    my @nametape = ([24, 101], [25, 102], [23, 103]);
    for my $arrayref (@nametape) {
        say "Arrayref values: ", $arrayref->[0], " and ", $arrayref->[
+1];
    }
'
Arrayref values: 24 and 101
Arrayref values: 25 and 102
Arrayref values: 23 and 103
