Udon Assembly Error when setting up audio play button

I’m trying to get a short sound clip to play in my world upon pressing a button, I followed a youtube tutorial and looked on the forums as to why it wouldn’t work, and then finally a noticed an assembly error

Expected data identifier.: Type: INT, Lexeme: [3], Literal: [3], Line: 12

it also continuously spats out errors in the console.

I have no idea what this means, this is my first time creating anything with udon.
