Variables declared with 'my' only become visible after the current statement has finished (ie. ended with ';'). Thus, under strictures, you must declare the variable on at least the statement before you use it.

I would probably use:

my $item = $self->grid($x, $y);
push @{$self->{'select'}}, $item if $item;
