I am facing "**number of bound variables does not match number of tokens**" exception while trying to use multiple condition in where clause using PDO.

code:
$servername = "localhost";
    $username = "xxxx";
    $password = "xxxxx";
    $dbname = "yyyy";

    $searchParam = $_POST['typeahead'];
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $stmt = $conn->prepare("SELECT * FROM trucks WHERE plate_number LIKE :plateNumber OR company_name LIKE: companyName");
        $stmt->bindValue(':plateNumber', '%'.$searchParam.'%', PDO::PARAM_INT);
    $stmt->bindValue(':companyName', '%'.$searchParam.'%', PDO::PARAM_INT);

Thanks for your help!
