Hai Monks, I am a perl beginner and trying to experiment on arrays. I came across this error in one of my experiment, Can't use an undefined value as an ARRAY reference at p42svn.pl line 844. The code is as shown below, 

@{$res{'act'}} = sort {
        return 0 unless $a->{'act'} =~ /^move/ and $b->{'act'} =~ /^mo
+ve/;
        return $a->{'act'} cmp $b->{'act'};  # add < delete
    } @{$res{'acts'}};

return \%res;

Thanks in advance
