WinCC VBS to open a picture screen attached in a pincture screen attached in a parent screen

Hi everyone, I'm going to try to explain my situation:

I'm working with WinCC v7.4 and I have several screens/picture screens attached one on another as I show in the pictures.

The fact is that I have a parent screen (named 01_00_00_Principal) where I use three picture screens: Principal1 (named 01_00_00_Principal1), Principal2 (named 01_00_00_Principal2) and Principal3 (named 01_00_00_Principal3). [Pic1]

Inside that Principal1 (named 01_00_00_Principal1) I have another picture screen Menu_superior (named 01_00_01_Menu_Superior). [Pic2]

And in that Menu_superior (named 01_00_01_Menu_Superior) I have a button with a VBS to show visibility of several objects I have back in Principal1 (named 01_00_00_Principal1), like a green circle or another Picture Screen. [Pic3]

My problem is that I can't make the VBS work, and I have tied with several codes I've found in this forum or trying to follow the manual like:

HMIRuntime.Screens("01_00_00_Principal").Screens("01_00_00_Principal1").ScreenItems("Circle").Visible = True

HMIRuntime.Screens("01_00_00_Principal.Principal1:01_00_00_Principal1").ScreenItems("Circle").Visible = True

Can anyone help me with this? Please!

I hope I managed to explain my situation correctly.
