Passing flashvars from parent SWF to child

I can’t for the life of me figure out why I cant get this to work. I can get my flashvars into the parent SWF but no from the parent to the child.

Anyone have any other ways other than appending the variables to the URL and ugin GET to pull them in?

Here it the line I’m using:
_level0.container_mc.f1Line1

_level0 is the parent

container_mc is the SWF container

and f1Line1 is the flashvars.
