Background Scroll Wont Work

I am creating a car game and the background scroll won’t work. I’m using the Scroller extension. The background offset block works, but not the scroll. I’m still working on it so the other code isn’t finished.

Here is the link to the game:

Here is a screenshot of the scrolling code:

The background is supposed to scroll down, but it doesn’t. Does anyone have a fix?

Also, the scroll suddenly stopped working. I’ve already adjusted the speed and it still doesn’t work

Fixed it! The reason why the background wouldn’t scroll is because the background offset is constantly being set to 0, so I changed it to where it isn’t constant.

thank you so much!
