MySql through Perl

Alright, I'm trying to use Perl to draw info from a web form and use it to create a new record in a database, the MySql statement works just fine if I use it manually in a SQL editor, but the CGI script just stops dead at the portion of the script that has the useage of the SQL statement in it, the problematic part is as follows:

$dbh = DBI->connect("dbi:mysqlPP:database=cvdvbe;host=192.168.10.30", "fosters_web", "webaccess", {'RaiseError' => 1}) or
     dienice("Can't connect: ",$dbh->errstr);

$sth = $dbh->prepare("insert into net_members values(NULL, 'new', '$b_name', '$b_add_1', '$b_add_2', '$b_city', '$b_state', '$b_zip', '$b_url', '$b_phone_a', '$b_phone_b', '$b_phone_c', '$b_phone_d', '$b_fax_a', '$b_fax_b', '$b_fax_c', '$b_contact', '$b_con_cell_a', '$b_con_cell_b', '$b_con_cell_c', '$b_con_email', '$b_naics', '$b_dvbe_num', '$b_dgs_num', '$b_dgs_exp_m', '$b_dgs_exp_d', '$b_dgs_exp_y', '$b_sb', '$b_sb_exp_m', '$b_sb_exp_d', '$b_sb_exp_y', '$b_mb', '$b_cmas', '$b_cmas_num', '$b_cmas_exp_m', '$b_cmas_exp_d', '$b_cmas_exp_y', '$b_dab_num', '$b_year_est');")


$dbh->errstr;


$rv = $sth->execute;
$sth->finish();

I don't know where the error is at exactly, since it doesn't generate an error, it just stops dead, doesn't go onto the next script, and doesn't create the entry, so can someone help me fix this, or tell me another way to do it?
