Vapor barrier wrong?

[Fillemar]

Hello!
I'm in the process of building a new inner ceiling in a room. As it stands today, there are studs, then strapping, and then the vapor barrier, and my question is whether it's okay to screw the drywall through the plastic into the strapping or if the two need to be switched?
So it would be studs, plastic, strapping, and then drywall.

The reason I'm asking is because I've already installed the vapor barrier, do I need to redo it or will it still work?

And insulation, of course, above the plastic*

The best thing is to have the plastic above the glesen

Is the rest of the house sealed, or is it only in this room that there is a vapor barrier?
