The shadowing is probably just a warning that results of your actual error.

That error tells you pretty clearly what you did wrong - you placed multiple statements after a case label.

You need to use brackets {} after a case if you want to place multiple statements into it.

What NaS said, also, the whole 'shadows a variable at a preceding level' warnings is all in regards for a multiple use of a variable with the same name globally and locally.

error 002: only a single statement (or expression) can follow each "case"
