Hi,
You already wrote the same exact post 4 times! Don't you think it's enough?

If you want someone help you, from my point of view it surely not the right way of doing, especially by writing Really Urgent. It just annoys people (and btw it seems not to be so urgent as you stay with it since the May12). If you want a "urgent" answer, hire a Flex expert or just be patient.
Kind regards,
Mich
