I have been stuck at the very same roadblock for many days (okay... so I do other things in between trying and re-trying).
I was so relieved to find this information... but somehow, even after studying this carefully and informing my actions accordingly... 'still the same problem.
I've tried a lot of variations. I'm missing something that is right under my nose... but what? What, if anything (important) is missing from the preceding? Frankly, I had already figured this out prior to seeing this... that must mean that I'm doing something wrong and I just don't see the difference between what I'm doing and what is written above. And yet... and yet... 'very strange! (and a little frustrating!) 
I know I'm going to get this sooner or later... Anybody have any suggestions/clarifications on the preceding posts? They seems plain enough to me... (and i you are thinking of posting (in french) but you can't be bothered to translate into english, by all means, please post in french! I will translate it for others in a follow up!
