in reply to Unique items in a text file

Use a hash, something like the following code 

my %erg = ();
while(<DATA>) {
    my @row = split(/,/,$_);
    ++$erg{$row[3]};
}
print $_ . ': ' . $erg{$_} . '<br />' . "\n" foreach (keys %erg); 
__DATA__

    Hi,
    I run the code and it is printing back the total for all the item just like the problem I was having before, but thanks for your effort.
    Result prints:
     48
