Script for VideoPlayer not working

I made a script for my world so that i have something like a playlist but nothing works at all!
This is my script’s code: sxcu.net - file jSXsE5qV.png

This is my Video Player in Unity. sxcu.net - file jSXtndxC.png
And this is my audio source sxcu.net - file jSXtyL3N.png

I tried finding a solution and posting on different forums but nobody answered so now im here

Is this player also synced and does it work with quest users?

yes and probably
