hello guys please help me with my code in login process there's an error message

Parse error: syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING)

in line $_SESSION['userid'] = $row['userid'];

Here's my complete code of loginprocess:

session_start(); 
$message = "";

if(count($_POST) > 0){
    $conn = mysql_connect("localhost", "root", "");
    mysql_select_db("etransmittal", $conn);
    $result = mysql_query("SELECT * FROM tbl_userlist WHERE username = '" . $_POST["username"] . "' AND user_password = '" . $_POST["password"] . "');
    $row = mysql_fetch_array($result);

    if(is_array($row)){
        $_SESSION['userid'] = $row['userid'];
        $_SESSION['username'] = $row['username'];
    }
    else{
        $message = "Invalid username or password";
    }
}

if(isset($_SESSION['userid'])){
    header("location: userhomepage.php");
}

</div>

You had one double quote missing, I have fixed it :

$result = mysql_query("SELECT * FROM tbl_userlist WHERE username = '" . $_POST["username"] . "' AND user_password = '" . $_POST["password"] . "'");
