What error message are you receiving when you turn debugging on?

I'm not sure if this is causing the problems, but you may want to not use special characters in your field names such as:

Prénom
Région

You will also want to remove the comma at the end of the last line:

Jeux => [10, 'alpha', '40x3', 500, 1, '', '']

Hope this helps.
