What do I do about "Use of uninitialized value" warnings?

I have some mistakes in my code. This code works locally but not on my server.

#Vérification de la concordance BD ->  Sons
for (my $k = 0; $k < scalar(@tableau_de_donnees); $k++) {
    my $donnee = $tableau_de_donnees[$k];
    if ($donnee) {
        my @une_donnee = split(/\./, $donnee);    #enlève l'extension
        for (my $l = 0; $l < scalar(@tableau_de_sons); $l++) {
            my $son    = $tableau_de_donnees[$l];
            my @un_son = split(/\./, $son);       #enlève l'extension
            if ($une_donnee[0] eq ($un_son[0])) {
                $trouver_son = "1";
            }
        }
        if ($trouver_son == "0") {
            print "Le fichier "
              . $tableau_de_donnees[$k]
              . " est introuvable. \n";
        }
        $trouver_son = "0";
    } else {
        print "Fin";
    }
}

Here is the log:

Use of uninitialized value in string eq at verif_db_physio.pl line 141, line 2.

Use of uninitialized value $son in split at verif_db_physio.pl line 139, line 2.

It looks to me like this:

my $son    = $tableau_de_donnees[$l];

should be this::

my $son    = $tableau_de_sons[$l];

You could avoid the problem entirely by changing

for (my $l = 0; $l < scalar(@tableau_de_sons); $l++) {
    my $son    = $tableau_de_donnees[$l];

to

for my $son (@tableau_de_sons) {
