Unknown Error when Deleting Records using PDO - php

Question

I am using this code which allows me to see my DB records in a table and in this table there is an option to delete or edit the records.
Only I get this error message and I can't figure out what I am doing wrong.
The error message:
Fatal error: Call to a member function prepare() on a non-object in C:\wamp\www\Inventaris++\NinjaCodeDelete.php on line 32
The code:
<?php
include'Connect2db3.php';
$action = isset($_GET['action']) ? $_GET['action']: "";
if($action=='delete'){ //if the user clicked ok, run our delete query
try {
$query = "DELETE FROM BCD WHERE id = ?";
$stmt = $conn->prepare($query);
$stmt->bindParam(1, $_GET['id']);
$result = $stmt->execute();
echo "<div>Record was deleted.</div>";
}catch(PDOException $exception){ //to handle error
echo "Error: " . $exception->getMessage();
}
}
$query = "SELECT ID, Categorie, SerieNummer, MacAdress, ProductCode, Prijs, RekNummer, PaletNummer, Hoeveelheid, Aantekeningen FROM BCD";
$stmt = $conn->prepare( $query );
$stmt->execute();
$num = $stmt->rowCount();
echo "<a href='reports.php'>View Reports</a>";
if($num>0){ //check if more than 0 record found
echo "<table border='1'>";//start table
echo "<tr>";
echo "<th>Categorie</th>";
echo "<th>SerieNummer</th>";
echo "<th>MacAdress</th>";
echo "<th>ProductCode</th>";
echo "<th>Prijs</th>";
echo "<th>RekNummer</th>";
echo "<th>PaletNummer</th>";
echo "<th>Hoeveelheid</th>";
echo "<th>Aantekeningen</th>";
echo "</tr>";
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
extract($row);
echo "<tr>";
echo "<td>{$Categorie}</td>";
echo "<td>{$SerieNummer}</td>";
echo "<td>{$MacAdress}</td>";
echo "<td>{$ProductCode}</td>";
echo "<td>{$Prijs}</td>";
echo "<td>{$RekNummer}</td>";
echo "<td>{$PaletNummer}</td>";
echo "<td>{$Hoeveelheid}</td>";
echo "<td>{$Aantekeningen}</td>";
echo "<td>";
echo "<a href='edit.php?id={$id}'>Edit</a>";
echo " / ";
echo "<a href='#' onclick='delete_user( {$id} );'>Delete</a>";
echo "</td>";
echo "</tr>";
}
echo "</table>";//end table
}else{
echo "No records found.";
}
?>
<script type='text/javascript'>
function delete_user( id ){
var answer = confirm('Are you sure?');
if ( answer ){
window.location = 'NinjaCodeDelete.php?action=delete&id=' + id;
}
}
</script>
I also want to say that I am not an advanced programmer I found this code online, where it seemed to be working for the other people who have used it.
I have some experience with Mysql and php but not with PDO.
I hope u can help me!
thank you in advanced.

What is inside your " include'Connect2db3.php'; "?
And with this I'm refering to connect2db3.php and is this file inside the right folder?
Your connection could look like this:
<?php
$config['conn'] = array(
'host' => 'yourHostName',
'username' => 'yourUserName',
'password' => 'yourPassword',
'dbname' => 'yourDBName'
);
$conn = new PDO('mysql:host=' . $config['conn']['host'] . ';dbname=' . $config['conn']['dbname'], $config['conn']['username'], $config['conn']['password']);
?>
