I have a speech window mock-up with the "show_two_window" as a slight overlay like this:

But when I actually try and implement it under "style.say_who_window" the window appears behind the text box like so:

(Theres not much to the code just
style.say_who_window.left_margin=150
style.say_who_window.ypos=400)
I looked into layers but I can't seem to find anything about layering elements in the options menu
I'm not looking to have different text boxes for every character so I tried simply making speaking characters have the mock-up version and allow the default window to not have the "say_who" box but then I couldn't get the "say_label" to move to the right position it wouldn't budge or would mysteriously vanish.
I've programmed before a bit before but I'm pretty new to renpy so I'm a little lost! I hope you can help me!
Thank you for you time
