DISPLAY GROUP - How to GET X/Y position of actual screen position when object is in a GROUP

Ok i have a sample app where my green alien is jumping up and down on platforms, I can tell if he is jumping or falling and he goes thru one way platforms no problem.

my platforms scroll down the screen as the user jumps on them in what I call an invisible player window where if he jumps to the top the I calculate the distance and scroll the group down.

My issue is that I need to be able to know the ACTUAL screen Y position and not the y position of the group. My group is defined larger than the screen so I can fill it with platforms and scroll turn it.

Anyone know how to get the Visible Y position of an object besides using the object.y ?

thanks
