This line is totally wrong:

28- AudioClip = scareSound;

AudioClip is a class and you can’t use it like that. You should create an instance of that class and then assign it, e.g.:

AudioClip someAudio = scareSound;

As I have no idea of what you are trying to achieve I can only guess that you want to replace those lines:

28- AudioClip = scareSound;
GetComponent<AudioSource>().Play();

on those:

AudioSource asrc = GetComponent<AudioSource>();
asrc.clip = scareSound;
asrc.Play();

If that’s not the case then let me know in the comment section below elaborating on your question or update your question with more info.
