Centred popup does not work in externally loaded swf

hello boys and girls…
Im about to crack out on this… I’m combining 2 tutorials, namely the “extrenally loaded swf’s with transition” and the “centered pop up window”

What I want to do is this: there is a button in one of the externally loaded swf. When the user presses this button, a centred pop up window is launched. It works fine when I take a look on the swf itself, but when its externally loaded, it doesnt do crap! why is this, how can I solve this?
is it because the _root.openWinCentre = function in the swf that is externally loaded is wrong or something?

Any advice anyone? thknzzz kos010
