in reply to Confused about "unitialized value" warning

Basically, it means that one of the variables that you use in that line contains no data. But as to which of them it is, we'd need to see more of the code.

Try printing them all out, one at a time, before that line.

    This is where I create my "matrix" variable. I presume this is where the problem comes from:

    while( my @row1 = $query1->fetchrow_array())
{
        push(@matrix, [@row1]);
        $count ++;
}

    Then I have a while loop

    $ab=0;
while ( $ab < $count)
{
      if ( $matrix[$ab][0] == $row[2])
      {
          if (1000 <= $total_packages)
          {
            push(@MASTER, $row[0].":".$row[1].":$matrix[$ab][3]:".$tot
+al_packages.":AI"); last SWITCH; }
            }
       $ab ++;
}

      You code isn't exactly easy to follow (we have <code> tags you know), but is it possible that some of the data you get back from DBI can contain NULLs? There would translate to Perl "undef" values.
