Since this is a field definition and not a method, the compiler expects a semicolon at the end of the statement.

Also, the challenge validator seems to be imposing some requirements that aren't part of the language syntax rules. In particular, it seems to need a space after the comma in the type specification :point_right: Func<int, int>

You might want to report this as a bug to the Support staff.
