asterisk users - Jul 2007 - Problem w/ MySQL update from perl AGI script

I've been trying to get a basic 5 question IVR survey working in an AGI
script,
and am having trouble with the SQL portion not updating the table. When I take
out all the AGI references, and run just the perl script, the table updates
with no problem(DBname,username,password have been substituted in this example
for the actual values):

#!/usr/bin/perl
#
#

use DBI;

$DATETIME = '123188765' ;
$TIMESTAMP = '8675309';

$dsn = "DBI:mysql:DBname;localhost;3306";
$dbh = DBI->connect($dsn,username,password);
$drh = DBI->install_driver("mysql");

my $Q1 = "8";
my $Q2 = "6";
my $Q3 = "7";
my $Q4 = "5";
my $Q5 = "3";

my $query = "INSERT into caller_data (DateTime, ANI, Q1, Q2, Q3, Q4, Q5)
 VALUES($TIMESTAMP,$ANI,$Q1,$Q2,$Q3,$Q4,$Q5)";


$sth = $dbh->prepare($query);
$sth->execute;
$sth->finish;





Then, When I try an put it together with the AGI commands, the IVR works nicely
from a caller prespective, but I get no update in the MySQL table:





#!/usr/bin/perl
#
#

use DBI;
use Asterisk::AGI;

$dsn = "DBI:mysql:DBname;localhost;3306";
$dbh = DBI->connect($dsn,username,password);
$drh = DBI->install_driver("mysql");


$AGI = new Asterisk::AGI;
my %input = $AGI->ReadParse();
my $ANI = $input{'CALLERIDNUM'};
my $TIMESTAMP = $input{'TIMESTAMP'};

$AGI->answer();

$AGI->stream_file('ABdeli-greeting');
$AGI->stream_file('ABdeli-instructions');
my $Q1 = $AGI->get_data('ABdeli-q1', 5000, 1);
my $Q2 = $AGI->get_data('ABdeli-q2', 5000, 1);
my $Q3 = $AGI->get_data('ABdeli-q3', 5000, 1);
my $Q4 = $AGI->get_data('ABdeli-q4', 5000, 1);
my $Q5 = $AGI->get_data('ABdeli-q5', 5000, 1);


my $query = "INSERT into caller_data (DateTime, ANI, Q1, Q2, Q3, Q4, Q5)
VALUES($TIMESTAMP,$ANI,$Q1,$Q2,$Q3,$Q4,$Q5)";


$sth = $dbh->prepare($query);
$sth->execute;
$sth->finish;

$AGI->hangup();
