Keep getting this error CS8025

I wrote this code in my BoardManager script

And i keep getting this error
Assets/Scripts/BoardManager.cs(8,1): error CS8025: Parsing error

And i dont know how to fix it :frowning:

Pls Help

P.S im pretty new to unity

Uhm, you have a curly opening bracket in line 8. In the scope of a script file you can only declare using statements (like you have at the beginning) or define one or multiple types / classes. Just an opening bracket makes no sense here. Remove it. It looks like you also have a “matching” closing bracket, remove that as well.
