I know I'm missing something but I can't see why I'm getting the error, Can't call method "proxy" on an undefined value at. Here's my code

open(my $fh, '<', 'cities.txt') or die $!;
    print $fh;
    open(my $prx, '<', 'proxies.txt') or die $!;
    print $prx;
    
    mkdir 'Bing', 0755;
    mkdir 'Bing/1Parsed/', 0755;
    mkdir 'Bing/1Parsed/Html/', 0755;
    
    chomp(my @cities = <$fh>);
    close($fh);
    
    chomp(my @prx = <$prx>);
    close($prx);

    open($fh, '<', 'keywords.txt') or die $!;

    for my $city (@cities) {
        seek($fh, 0, 0);

        while (my $keywords = <$fh>) {
            chomp($keywords);
            print "$city $keywords\n";

    my $xml1 = $link1 . $city ."+". $keywords . $link2 . $city ."+". $
+keywords . $link3;
    #my $xmla = $link3 . $row . ".com";
    #my $xmlx = $link4 . $row;

    my $filename1 = "Bing/".($city)."_". ($keywords) . ".html";
    open my $fh1, ">", $filename1 or die("Could not open file. $!");
    
    #toggle proxy selection
    my $prx=$_;

    my $ua->proxy('http', $prx);
    $ua->agent('Mozilla/8.0');
    print "using:";
    print "proxy";
    print $prx;

The above is a piece of a sub script in a bigger script. Any guidance is greatly appreciated
