You might have more luck doing 
$sth = $dbh->prepare(
    "insert into $tblname (product_id, model_number, description)
     values (?, ?, ?)");
    $sth->execute($prod_id, $mod_num, $data);

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
