Question

Answer

Nearly, but there are one or two things to fix. You can't run on another main clause after that first comma; you must either replace it with a semicolon or a full stop / period. You also need a full stop after each of your other sentences. "Fortunately" is spelled thus, and it should be "he was alright" rather than "he was right".
