This is SSCCE example code. At the position (A) in the code, I am asking subroutine check_mobiletype to find the ID, and phone number. It does find the ID and phone, at position (B). I don't know why, but at position (C) it says: "Use of uninitialized value $phone in say"...

So, I get kind of dizzy feeling, and trying to find a solution.

#!/usr/bin/perl 

my $destination = '+123';

if($destination eq 'show') {
    $show = 1;
    $destination = shift @ARGV;
    utf8::decode($destination);
    $sms = join(" ", @ARGV);
    # POSITION (A)
    my ($id, $phone) = check_mobiletype($destination) || die "ID not f
+ound";
    # POSITION (C)
    print $id, $phone, "\n"; # ID is not printed
} else {
    $sms = join(" ", @ARGV);
    die "No text" unless $sms;
    my ($id, $phone) = check_mobiletype($destination) || die "ID not f
+ound";
    print $id, ' ', $phone, "\n";
}

exit;

sub check_mobiletype {
    my $destination = shift;
    if($destination =~ /^\+/ && $destination !~ /^\+{1}.*\D/) {
        print "Type phone number\n";
        my $id = get_contacts_id_by_mobilephone($destination) || retur
+n 0;
        my $phone = get_mobilephone($id) || return 0;
        # POSITION (B)
        print $id, ' ', $phone, "\n"; # ID and phone are printed
        return ($id, $phone);
    } elsif($destination =~ /\d/ && $destination !~ /\D/) {
        #say "Type ID";
        my $id = $destination;
        my $phone = $tcrm->get_mobilephone($id) || return 0;
        return ($id, $phone);
    }
}

sub get_mobilephone {
    return '+49121212121';
}

sub get_contacts_id_by_mobilephone {
    return 123456;
}
