tabel not closing

My ISP reported that one of my tables didn't close properly "
client is using or hasn't closed the table properly". We have used the same scrip (queries) for some time.

Does anyone see a problem with this script?


if ($txn_type == "cart"){
$strQuery = "insert into paypal_payment_info(paymentstatus,buyer_email,firs tname,lastname,street,city,state,zipcode,country,m c_gross,mc_fee,memo,paymenttype,paymentdate,txnid, pendingreason,reasoncode,tax,datecreation) values ('".$payment_status."','".$payer_email."','".$firs t_name."','".$last_name."','".$address_street."',' ".$address_city."','".$address_state."','".$addres s_zip."','".$address_country."','".$mc_gross."','" .$mc_fee."','".$memo."','".$payment_type."','".$pa yment_date."','".$txn_id."','".$pending_reason."', '".$reason_code."','".$tax."','".$fecha."')";

$result = mysql_query($strQuery) or die("Cart - paypal_payment_info, Query failed:<br>" . mysql_error() . "<br>" . mysql_errno());
