I found it here: http://www.ticketnet.fr/shop/fr/manif.a ... creTopPage
You can actually try to get a better idea of how the seating is arranged by going to the site. Pretend you're going for a Carré Or ticket and there is a type of zoom option which shows you where the seat is so you can choose.
Let me know if it doesn't work for you and I'll try and locate your seat tomorrow.

Edit: Sorry Mabeanie1, just realised that you had already recommended that website, silly me!
