dies at last line

my $db = DBI->install_driver('mysql')
    or die;
my $ipplan = DBI->connect('DBI:mysql:host=[URL unfurl="true"]www;database=ipplan','xxxx','xxxxx')[/URL]
    or die;
my $C = $ipplan->prepare("SELECT count(*),sum(if(lastpol > ?,1,0)) as recent  FROM ipaddr WHERE baseindex = ?")
    or die;
my $L = $ipplan->prepare("SELECT max(lastpol)  FROM ipaddr WHERE baseindex = ?")
    or die
my $B = $ipplan->prepare("SELECT * FROM base WHERE subnetsize > 1 ORDER BY baseaddr")
    or die;
die unless $C && $L && $B ;
