Insert variabel sendt fra Flash via PHP service, hvor er fejlen?

PHP: Modtager object $rs fra Flash.
<?php
class test{
    var $dbhost = "localhost";
    var $dbname = "*";
    var $dbuser = "*";
    var $dbpass = "p*";
    function test(){
        $this->methodTable = array(
          "setItems" => array(
                "description" => "Insert i MySql",
                "access" => "remote", // available values are private, public, remote
                "arguments" => array ("rs")
            )
        );
        // Initialize db connection
        $this->conn = mysql_pconnect($this->dbhost, $this->dbuser, $this->dbpass);
        mysql_select_db ($this->dbname);
      }
    function setItems($rs){
        $sql = "INSERT INTO test (var) VALUES ('".$rs['vari']."'";
          mysql_query($sql);
  }
}
?>

Er der fejl i $sql?
