Hi Monks, I have a very weird problem. Basically, I am trying to update a "cell" in an array of array. e.g. @unique_manufacturer_model->[$i][12]++ Somehow, the exact row/column of another cell (in another array) is also being updated with the same value. I've tried changing the name of the array but does'nt work. The routine printing out the result is confirmed working fine. I just ca'nt understand why updating this array will affect another array of a different name. As you can see below, I do'nt know how the result 5,36,1 can appear in the other array. Here's the code snippets: 
for my $i (0 .. $#unique_manufacturer_model) {
    for my $j (0 .. $#unique_terminal_id) {
        if ( (@unique_manufacturer_model->[$i][9] eq @unique_terminal_
+id->[$j][9]) and (@unique_manufacturer_model->[$i][10] eq @unique_ter
+minal_id->[$j][10]) ) {
            if (@unique_manufacturer_model->[$i][12] eq "") {
                @unique_manufacturer_model->[$i][12] = 1;
            }
            else {
                @unique_manufacturer_model->[$i][12]++;
            }
        }
    }
}
&checkpoint(9,10,12,@unique_manufacturer_model);

&checkpoint(10,11,12,@unique_manufacturer_model_version);


And here's the output:

[root@localhost cron]# perl probe_cron.pl
