第27行的validate.php中出现一个错误

$connexion->execute(array($_GET["reponse2"]));

我有2页，第一个名为inscription.php，没有错误。在第二页（validation.php）上，第27行出现一个错误

$connexion->execute(array($_GET["reponse2"]));

Validation.php：

<?php

$bdd = new PDO('mysql:host=localhost;dbname=inscription;charset=utf8', 'root', '');

$reponse = $bdd->query('SELECT * FROM validation');

while($validation = $reponse->fetch()) {

    echo 'Pseudo: ';
    echo $validation['pseudo'];
    echo ' E-mail: ';
    echo $validation['email'];

    echo '<a href="validation.php?action=accepter&id='.$validation['id'].'">Accepter </a>'; // Il y a une espace pour séparer les liens.
    echo '<a href="validation.php?action=refuser&id='.$validation['id'].'">Refuser</a>';

    echo '<br/>';
}


if(isset($_GET['action']) AND isset($_GET['id'])) {
$action = $_GET['action'];
    if($action == "accepter")
    {
        $id = $_GET['id'];
        $reponse2 = $bdd->prepare("SELECT * FROM validation WHERE id='$id'");
        $connexion->execute(array($_GET["reponse2"]));

        $pseudo = $connexion['pseudo'];
        $passe = $connexion['passe'];
        $email = $connexion['email'];

        $bdd->query("INSERT INTO connexion VALUES('$id', '$pseudo', '$passe', '$email')");

        $bdd->query("DELETE FROM validation WHERE id='$id'");
    }
    elseif($action == "refuser") {
        $id = $_GET['id'];
        $bdd->query("DELETE FROM validation WHERE id='$id'");
    }
}
?>

错误是：

注意：未定义的变量：第27行的D：\ xampp \ htdocs \ inscription \ validation.php中的连接

致命错误：未捕获错误：在D：\ xampp \ htdocs \ inscription \ validation.php：27中对null调用成员函数execute（）堆栈跟踪：＃0 {main}抛出在D：\ xampp \ htdocs中\ inscription \ validation.php，第27行
