Space shooter tutr script error in console

Thanks for looking and yes I'm a nub to game creation and scripting. Everything has been going great until scripting time. When ever I started scripting, at some point my MacbookPro starts crashing. I think it maybe Unity constantly updating from the script editor.

Anyway I deleted my script and stopped the crashes. So now I've opened up the supplied "Done" script and get these errors.

Assets/Scripts/PlayerController.js(1,6): UCE0001: ';' expected. Insert a semicolon at the end.

Assets/Scripts/PlayerController.js(2,6): UCE0001: ';' expected. Insert a semicolon at the end.

Assets/Scripts/PlayerController.js(4,22): UCE0001: ';' expected. Insert a semicolon at the end.

Assets/Scripts/PlayerController.js(7,16): BCE0043: Unexpected token: float.

Assets/Scripts/PlayerController.js(7,22): BCE0044: expecting EOF, found 'xMin'.

This is what this console is complaining about after I c/p the "Done Player Controller" script.

Any ideas? I also ran the the "Start Debugging" in Mono. Same thing.

Thanks Greg
