将我的收音机的值插入数据库

I can insert the values of the radio's in the database but it only works if I have selected the radio 'vrouw' and if select 'man' it does not insert into the database.

Php function:

if (isset($_POST['submitForm'])) {

    $dbhost = "localhost";
    $dbname = "schoolopdrachten";
    $dbusername = "root";
    $dbpassword = "";

    $link = new PDO("mysql:host=$dbhost;dbname=$dbname",$dbusername,$dbpassword);

    $stmt = $link->prepare("INSERT INTO javascript (naam, gender, land, provincie, suboptionman, suboptionvrouw) VALUES (:naam, :gender, :land, :provincie, :achternaam, :suboptievrouw)");

    $stmt->bindParam(':naam', $_POST['inputName']);
    $stmt->bindParam(':gender', $_POST['keuzegender']);
    $stmt->bindParam(':land', $_POST['select1']);
    $stmt->bindParam(':provincie', $_POST['select2']);
    $stmt->bindParam(':achternaam', $_POST['keuzeMan']);
    $stmt->bindParam(':suboptievrouw', $_POST['keuzeVrouw']);

    $stmt->execute();
}
