When you say you’re new to Unity, I presume you also mean you’re completely new to C# because this is a syntax error using C#. The error is telling you which line (17) and column (32) is missing an expected ; character so there’s not much else to understand TBH.
Mostly though, look at the line or the preceeding line because you’re likely to have made a typo. The compiler won’t forgive you either, it has to be exact and the correct case.
Take a look on the line. “nem” isn’t correct right? It’s supposed to be “new”
