Karting Game Tutorial

Hello, I’m trying to learn FMOD into Unity with the Karting game tutorial, and I was in the part where it says to delete some code lines on a few scripts, and when i did how it says, it tells me there is an error, and now I can’t go back to the original scripts, and there isnt anything anywhere to tell me what is wrong. How can i fix this without having to delete everything from the game files.

Are you able to post the errors you are getting and the script you deleted the section from?
